A girl calculates 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

Solution:

Probability can be defined as the ratio of the number of favorable outcomes to the total number of outcomes of an event.

Consider x as the number of tickets bought by the girl

From the question we can write it as

x/6000 = 0.08

By cross multiplication

x = 0.8 × 6000

x = 480

Therefore, she bought 480 tickets.
