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 probability of getting three tails and a head when a coin is tossed four times?

The probability is 1/4


What is the probability of getting 3 heads and 3 tails if a fair coin is tossed 6 times?

only about 75% because very often it is not equal The probability of 3 heads and 3 tails is 0.3125


What is the probability of a coin tossed 6 times to have 3 heads and 3 tails?

50/50


What is the probabilty if a coin is tossed three times?

The probability of the coin coming up heads each time is 1/8; likewise for 3 tails. The probability of getting 2 heads and 1 tail (in any order) or 2 tails and 1 head, is 3/8. There are lots of other events whose probability can be calculated when a coin is tossed 3 times, but the question doesn't specify what event is to have its probability calculated.


What is the probability of getting exactly 3 heads if a fair coin is tossed 8 times?

The probability to get heads once is 1/2 as the coin is fair The probability to get heads twice is 1/2x1/2 The probability to get heads three times is 1/2x1/2x1/2 The probability to get tails once is 1/2 The probability to get tails 5 times is (1/2)5 So the probability to get 3 heads when the coin is tossed 8 times is (1/2)3(1/2)5=(1/2)8 = 1/256 If you read carefully you'll understand that 3 heads and 5 tails has the same probability than any other outcome = 1/256 As the coin is fair, each side has the same probability to appear So the probability to get 3 heads and 5 tails is the same as getting for instance 8 heads or 8 tails or 1 tails and 7 heads, and so on

What is a probability of getting a two tails in first two chances if coin is tossed 10 times simultaneously?

The probability of getting two tails in the first two is 1/4. And it does not matter how many more times the coins are tossed after the first two tosses.


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%.


If a coin is tossed two times what is the probability of getting tails two times in a row?

25% or 0.25 Probability of one tail is 0.50. Since two tails are independent events, the probability is 0.5 x 0.5 = 0.25


What is the probability of getting 3 heads and 3 tails if a fair coin is tossed 6 times?

only about 75% because very often it is not equal The probability of 3 heads and 3 tails is 0.3125


A coin is tossed 4 times. What is the probability of getting tails 4 times in a row?

The probability to get tails once is 1/2 (for a fair coin) The probability to get tails twice = the probability to get it once x the probability to get it a second time The probability to get tails 4 times in a row is (1/2)4=1/16 The probability to get tails n times in a row is (1/2)n=1/2n The same thing is also true for heads (same probability: 1/2 each time)


What is the probability of a coin tossed 6 times to have 3 heads and 3 tails?

50/50


When A fair coin is tossed three times. Find the probability of getting a head on the first toss and tails on the second and third tosses?

It is 1/8.


If a coin is tossed 4 times and heads comes up all 4 times the probability of getting heads on the fifth try is?

0.5, 1/2, 50% The probability for heads versus tails does not change based on the amount of times the coin is tossed. It will always be a 50% chance.
