Question

According to an​ airline, flights on a certain route are on time 80​% of the time. Suppose 17 flights are randomly selected and the number of​ on-time flights is recorded.

The probability that fewer than 11 flights are on time is ___?____ (Round to four decimal places as needed)

Expert Solution
Step 1

p(flight on time) = p = 0.80

n = 17

flights selected

x = No. of flight on time

 

p(x=X) = nxC  px qn-x             - binomial distribution(∵ fixed No. of trials, probability constant, independent events)
