Question

Now say you sample 10 independent customers. What is the probability that exactly 5 of them will take more than 3 minutes to check out their groceries? Round to the nearest tenths/first decimal place, 0.x

The amount of time in minutes that it takes for a randomly selected customer to finish checking out
their groceries is a continuous uniform random variable (that is to say it follows a uniform
distribution) on the interval 0 to 5 minutes. That is to say that f(x)=1/5=0.2 for x in (0,5) and 0
otherwise.
