Question

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

Answer 1

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

Answer 2

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% .
