In 2017, approximately 142,650 of the 188,000 Fairfax County Public School students were eligible to ride the bus each day to or from 16,086 bus stops. (That equates to more than 25 million individual trips each school year!)

A sample of 100 students is randomly selected. Let k be the expected number of bus riders in this sample.

Find k. Round your answer to the nearest whole number.

Obavezno

Hence, find the probability that exactly k students ride the bus.
