Question

Write the probability of getting 2 heads when flipping a coin 2 times. (Write as a reduced fraction)

Answer 1

we have that

The probability of getting 1 head when flipping a coin one time is

P=1/2

so

the probability of getting 2 heads when flipping a coin 2 times is

P=(1/2)*(1/2)=1/4

therefore

the answer is

P=1/4
