(b) 240
(c) 480
(d) 750
correct answer : (c) 480
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
