Question

If you toss a fair coin 7 ​times, what is the probability of getting all​ heads? Express the probability as a simplified fraction.

A) 1/256
B) 1/2
C) 1/128
D)1/64

Answer 1

Explanation:

When you flip a coin, the possibilities are that you either get a heads or a tails. The probability of getting a heads in 1 flip then is 1/2. If you do this 7 times, the probability is

`((1)/(2))^7` which is 1/128, choice C
