2. The probability that a car will come to a complete stop at a particular stop sign is 0.4. Assume that the next four cars arrive at the stop sign are independent of one another. Find each of the following probabilities:
a) None of the four cars come to a complete stop?

Step-by-step explanation:

This can be solved using the binomial distribution because the cars arriving at the stop are independent of each other. This means we will use:

Where p is the probability of success, q = 1 - p is the probability of failure and n is the number of cars sampled.

p = 0.4

q = 0.6

n = 4

Therefore,

This is equal to

-232
