What is the probability of getting 2 heads when 2 coins are tossed?
The probability of tossing two heads in two coins is 0.25.
If n coins are tossed simultaneously what is the probability that they are all show heads?
(0.5)n
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
A die is tossed. Find the odds against rolling a number greater than 1.?
The probability of rolling a number greater than 1 is 5/6.
When two coins are tossed simultaneously what is the probability of obtaining at most one head?
The probability is 3/4.
What is probability of obtaining a number different from 11 when a single fair die is tossed?
A single fair die has the numbers 1 to 6, so when a single fair die is tossed the probability of obtaining a number different than 11 is: P(x diff than11) = 1.
What is the probability of obtaining tails or a six?
The answer depends on the experiment: how many coins are tossed, how often, how many dice are rolled, how often.
If a die is tossed once probability of it landing on a 6?
Since there are 6 possible outcomes, and you want the probability of obtaining one of the outcomes (in your case 6), the probability of it landing on a 6 is 1/6.
Probability is the what that something will or will not occur?
Probability is the likelihood that something will occur. If you subtract it from 1, we get the likelihood (or probability) that it will not occur. If a coin is tossed and rolls heads 6 times, the (empirical) probability of obtaining a head is 6/10 or .6. 1-.6 =.4 is the empirical probability (or likelihood) of not getting a head.
What is probability of obtaining a number different from 12 when a single fair die is tossed?
assuming we are talking about standard dice here (six sided, numbered 1-6) then the probability of obtaining a result other than 12 when a single die is tossed is 100%. There is no way to roll a 12 after 1 toss of 1 die, therefore the chance of getting anything other than 12 is guaranteed
If 4 coins are tossed what is the probability of 4 tails?
The probability is 1/16.
Probability of gettingm 2 tails when 2 coins are tossed?
1/4 if they are tossed only once.
An ordinary die is tossed four times what is the probability of obtaining a number greater than 4 at least once?
1 - (2/3)4 = 1 - 16/81 = 65/81 ≈ 80.25%
Probability of getting both head and tail simultaneously when a coin is tossed?
The probability is 50-50.
If a coin is tossed then what is the probability that the number is 5?
Coins do not have numbers, there is only the probability of heads or tails.
If a coin is tossed 5 times what is the probability of getting tails no more then 2 times?
The probability is 0.5The probability is 0.5The probability is 0.5The probability is 0.5
