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

The sample proportion

                                p = \frac{x}{n} = \frac{15}{25} = 0.6

Let 'X' be the binomial distribution

Given sample size 'n' = 10

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

                                 μ = n p

                                    = 10 × 0.6

                                   = 6

<u><em>Conclusion</em></u>:-

<em>Expected number of students  would have a driver's license = 6</em>
