Question

Tossing a regular coin 3 times, what is the probability of getting heads every time? 4)

Answer 1

The probability of getting heads on the first toss is  1/2 .

Then, the probability of getting heads on the second toss is  1/2 .

Then, the probability of getting heads on the third toss is  1/2 .

The probability of all three things happening is ...

                 (1/2) x (1/2) x (1/2)  =  1/8  =  0.125  =  12.5% .

Answer 2

1/2 times 1/2 times 1/2 would be 1/8. in percentage, 12.5%
