Question

Claire is going to flip a coin 3 times. What is the probability of getting tails up on the first flip and heads up on both of the last 2 flips

Answer 1

1/8

Explanation:

A coin has two sides, 1 called heads, the other called tails.

The first coin flip Claire wants a tails. She has a 1/2 chance of getting tails.

The second coin flip Claire wants heads. She has a 1/2 chance of getting heads.

The third coin flip Claire wants heads. She has a 1/2 chance of getting heads.

Now, multiply the fractions together:

1/2 x 1/2 x 1/2 = 1/(2 x 2 x 2) = 1/8

1/8 is the probability of getting that order.
