Question

Ques. the probability of drawing an apple from a bag of fruits is 6/25. how many apples should ravi draw, so that there is a chance he will draw 12 apples on average?

Answer 1

Let , 
Ravi draw n fruits

As the probability of drawing an apple from the bag is 6/25 , the probability of each fruit drawn by ravi being an apple is also 6/25.

As he drew n fruits , the average number pf apples would be  6/25 * n

we want it to be 12.

So , equating (6/25)*n to 12

ie (6/25)*n = 12

n = 50.
