In a class of 25 students, 15 of them have a driver's license. If ten students are randomly selected, what is the expected number of students that would have a driver's license?

Expected number of students  would have a driver's license = 6

Step-by-step explanation:

Explanation:-

Given data In a class of 25 students, 15 of them have a driver's license

The sample proportion

Let 'X' be the binomial distribution

Given sample size 'n' = 10

mean of the binomial distribution or expected number of students  would have a driver's license

                                 μ = n p

                                    = 10 × 0.6

                                   = 6

Conclusion:-

Expected number of students  would have a driver's license = 6
