Question

There are 8 cars in a parking lot on a very cold day. Suppose the probability of any one of them not starting is 0.14. What is the probability that exactly 3 of the cars will not start?

Answer 1

I got 0.072 or 7.2%

Answer 2

(nCk) × (p)^n × (1 - p)^(n - k)

(₈C₃) × (0.14)³ × (1 - 0.14)⁵ = 0.072

Answer 3

a probability is a number between 1 and 0 , so its not the % stuff

and the rest of it looks fine as well

Answer 4

Thanks again :)
