Drivable Streets According to a USA Today Snapshot, drivers say fixing or repaving streets is the best way to make their communities drivable—better than building new roads or adding lanes.14 Suppose that n = 15 drivers are randomly selected and x is the number who say that improved road conditions would make their communities more drivable. Let p= .4 when finding probabilities associated with any following outcomes:

What is the probability distribution for x?

b. What is P(x ≤ 4)?

c. Find the probability that x exceeds 5.

d. What is the largest value of c for which P(x≤c) ≤ .5?
