If you alternate between flipping a coin and rolling a die what is the probability of rolling a 2 before flipping a heads?
The probability of rolling a 2 on a die before flipping a heads on a coin is 1 in 12. The probability of rolling a 2 is 1 in 6. The probability of flipping heads is 1 in 2. Since these are sequentially unrelated events, you simply multiply the probabilities together.
What is the probability of flipping four coins and getting heads twice?
Well, you have 24 possibilities, and you can get heads 6 ways, so it is 1/4.
What is used to determine the probability of two indepepdent events occurring?
Multiply together the probability that each event would have of occurring by itself. For example, the probability of rolling a "3" on a single die is 1/6 ,because there are 6 different possibilities. And the probability of flipping a "heads" on a coin is 1/2 , because there are two possibilities. Then the probability of rolling a "3" AND flipping a "heads" is ; 1/6 x 1/2 = 1/12 .
What is the probability of rolling 3 on a dice and flipping a coin to heads?
a three on a dice is 1/6 and aheads on a coin is 50%
What is the probability that you get 2 heads and 3 tails after flipping a coin 5 times?
1:6 * * * * * No. It is 10/32 = 5/16
