What is the probablity that the sequence will be heads-heads-heads if you toss a coin 3 times?
the probability of getting heads-heads-heads if you toss a coin three times is 1 out of 9.
What is the probability of getting heads at least once if a fair coin is flipped three times?
7/8
The probability of flipping a coin three times and getting two heads is?
There are 8 permutations of flipping a coin 3 times, or of flipping 3 coins one time. They are, with the permutations of two heads bolded...TTTTTHTHTTHHHTTHTHHHTHHH... thus, the probability of flipping a coin 3 times and getting 2 heads is 3 in 8, or 0.375.
What is the probability of getting at least 2 heads when flipping a coin 3 times?
.125
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.
When a coin is tossed three times what is the probability of getting at most two heads?
The opposite of getting at most two heads is getting three heads. The probability of getting three heads is (1/2)^2, which is 1/8. The probability of getting at most two heads is then 1 - 1/8 which is 7/8.
What is the probablity that the sequence will be heads-heads-heads if you toss a coin 3 times?
the probability of getting heads-heads-heads if you toss a coin three times is 1 out of 9.
What is the probability of you getting three heads straight for tossing a fair coin three times?
It is 1/8 = 0.125
What is the probability of getting tails once and heads three times if you flip a coin four times?
25:75
A coin is tossed five times find the probability of getting exactly three heads?
Since a coin has two sides and it was tossed 5 times, there are 32 possible combinations of results. The probability of getting heads three times in 5 tries is 10/32. This is 5/16.
What is the probability of getting three heads in tossing a coin three times?
It is (1/2)3 = 1/8 or 0.125
What is the probability of getting heads at least once if a fair coin is flipped three times?
7/8
What is the probability of flipping a coin 3 times and getting 3 heads?
The probability of flipping a coin 3 times and getting 3 heads is 1/2
What is the probability of getting all heads or all tails if you flip a coin three times?
The probability of getting all heads if you flip a coin three times is: P(HHH) = 1/2 ∙ 1/2 ∙ 1/2 = 1/8. The probability of getting all tails if you flip a coin three times is: P(TTT) = 1/2 ∙ 1/2 ∙ 1/2 = 1/8. The probability of getting all heads or all tails if you flip a coin three times is: P(HHH or TTT) = P(HHH) + P(TTT) = 2/8 = 1/4.
What is the probability of tossing a coin three times and getting it on heads each time?
Each toss has a 1/2 probability of getting heads. Each toss is an independent event. So three heads in a row (heads AND heads AND heads) would have a probability of:1/2 * 1/2 * 1/2 = (1/2)^3 = 1/(2^3) = 1/8 = 12.5%
A fair coin is tossed three times find the probability of getting exactly 2 heads?
3 out of 8
