The sample space is HH, HT, TH, HH. Since the HH combination can occur once out of four times, the probability that if a coin is flipped twice the probability that both will be heads is 1/4 or 0.25.

A polynomial of degree zero is a constant term

The grouping method of factoring can still be used when only some of the terms share a common factor A True B False

The sum or difference of p and q is the of the x-term in the trinomial

A number a power of a variable or a product of the two is a monomial while a polynomial is the of monomials

What is the chance that that 2 flipped coins both come up heads?

The probability that 2 flipped coins both come up heads is 0.52 or 0.25


Arnold flipped a coin twice and it landed heads up both times If he flips the coin again What is the probability the coin will land heads up?

The correct answer is 1/2. The first two flips do not affect the likelihood that the third flip will be heads (that is, the coin has no "memory" of the previous flips). If you flipped it 100 times and it came up heads each time, the probability of heads on the 101st try would still be 1/2. (Although, if you flipped it 100 times and it came up heads all 100 times - the odds of which are 2^100, or roughly 1 in 1,267,650,000,000,000,000,000,000,000,000 - you should begin to wonder about whether it's a fair coin!). If you were instead asking "What is the probability of flipping a coin three times and having it land on "heads" all three times, then the answer is 1/8.


What is the probability of flipping a coin twice and getting two heads?

The probability is 25%. The probability of flipping a coin once and getting heads is 50%. In your example, you get heads twice -- over the course of 2 flips. So there are two 50% probabilities that you need to combine to get the probability for getting two heads in two flips. So turn 50% into a decimal --> 0.5 Multiply the two 50% probabilities together --> 0.5 x 0.5 = 0.25. Therefore, 0.25 or 25% is the probability of flipping a coin twice and getting heads both times.


A coin is tossed twice what is the probability that it will show heads both times?

The probability is 0.25.Look at it this way--if you toss a coin twice, there are four equally-probable outcomes:tails, tailstails, headsheads, tailsheads, headsSo the probability of heads twice in a row is one in four, or 25%.the chance of tossing heads is 1/2 (50%) The chance of tossing the next heads is 1/2 (50%) 1/2 x 1/2 = 1/4 (25%)


A coin is tossed twice what is the probability that it will show heads both times -?

1/2 x 1/2 = 1/4


What is the probability that exactly two times head are being tossed?

The answer depends on how many times the coin is tossed. The probability is zero if the coin is tossed only once! Making some assumptions and rewording your question as "If I toss a fair coin twice, what is the probability it comes up heads both times" then the probability of it being heads on any given toss is 0.5, and the probability of it being heads on both tosses is 0.5 x 0.5 = 0.25. If you toss it three times and want to know what the probability of it being heads exactly twice is, then the calculation is more complicated, but it comes out to 0.375.


Two coins are tossed What is the probability of both coins are heads?

The probability that both coins are heads is the probability of one coin landing heads multiplied by the probability of the second coin landing heads: (.5) * (.5) = .25 or (1/2) * (1/2) = 1/4


What is the probability of flipping 2 coins and having both show heads?

If both tosses are fair, the probability of that outcome is one in four.


Which result is the least likely if a coin is flipped 10 times?

Both heads and tails are equally likely.


What is the probability of tossing two coins and getting heads on both?

1/2


If you flip two coins the probability that both will come up heads is?

one fourth


What are the odds in favor of getting 2 heads when a coin is tossed twice?

One in four. 1:4. The probability of getting heads when a fair coin is tossed is: P(H) = 1/2. The probability of getting heads on a second toss is: P(H) = 1/2, this result is independent of the result of the first toss. The probability of having both events happen (heads on the first and heads on the second toss) is: P(H1UH2) = (1/2)∙(1/2) = 1/4 = 0.25 = 0.25%


What is the probability that a dime and penny are tossed in the air both that both land on heads?

One out of every four flips


A fair nickel and a fair dice are tossed once outcomes match when both coins land on heads or both coins land on tails What is the theoretical probability of a match?

The probability of 2 coins both landing on heads or both landing on tails is 1/2 because there are 4 possible outcomes. Head, head. Head, tails. Tails, tails. Tails, heads. Tails, heads is different from heads, tails for reasons I am unsure of.

What is the probability of roling an even number on the number cube and flioing heads on the coin?

0.5 in each case. The probability of both happening simultaneously is 1/4


What is the probability of getting tails twice in a row?

The probability of tossing a coin twice and getting tails both times is 1 in 4, or 25%. If you have already tossed a coin and had it land on tails, the probability that it will land on tails again the next time you toss it is 50%.


What is the probability of rolling an odd number OR getting a heads when rolling a die and tossing a coin?

fifty fifty for both.


What is the probability of drawing a black card from a 52 card deck and flipping heads on a coin?

Half the cards in a standard pack are black. Therefore the probability of drawing a black card is 1/2. Half the sides of a coin are "heads" so again the probability is 1/2. Therefore the probability you will both draw a black card and flip heads = 1/2 * 1/2 = 1/4.


In statistics which is better large sample size or small sample size?

Generally, the larger the sample the more reliable the results. Example: If you flipped a coin twice and got heads both times you could say the coined is biased towards heads. However, if you repeat the experiment 100 times your results will be a lot more reliable.


Two events in which eitherone or the outher must take place but they can't both happen at the same time The probability is 1?

This is correct. For example the probability of tossing a coin so that it comes up heads is 1/2 and the probability that it comes up tails is also 1/2. The probability that it will come up either heads or tails is 1.


What is the probability that a single coin flip will come up heads on the first two flips?

The probability of heads on the first flip is 50%.The probability of heads on the second flip is 50%.The probability of both is (50% x 50%) = 25% .=========================================Another way to look at it:Two tosses can come up in four different ways:H HH TT HT TOnly one of these . . . H H . . . counts as success.1 out of 4 = 25% .
