Question

In a sample of 300 students what is the probability of seeing 10 percent of the students choosing sports when it is known that on an average 25 students out of 300 choose sports. It is assumed that selection of sports as an option for each student is an independent event.

Answer 1

10%of 300is 30.
$(p) = \frac{ favourable \: outcome}{total \: no. \: of \: outcome}$
30/300=1/10
