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?

The answer is 16.64 feetyour welcome

The question is kind of confusing. if it's asking how many variations of answers can you give. then do 4^5 for your answer.this would be something like the first question could be a and the 2nd c or first b next c etc. if you can, ask the teacher for a better confirmation of what it's asking. if i'm assuming correctly what it's asking, it's 625 different variations.
