question : 6. A girl calculate that the probability of her winning the first prize in a lottery is 0.08. If 6000 tickets are sold, how many tickets has she bought ?

(a) 40
(b) 240
(c) 480
(d) 750

explanation of answer : as we know the formula of probability is

probability = tickets has she bought/Total tickets

given probability = 0.08 and Total tickets = 6000

putting the values of probability and Total tickets in the formula.

0.08 = tickets has she bought/6000

tickets has she bought = 6000  x 0.08

Tickets she has bought =  6000  x 0.08 = 480

that is why we have marked (c) 480 as our correct answer.
