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

As we know that,

Here in this case,

P(E) = 0.08

No. of favorable outcomes =?

Total no. of possible outcomes = 6000

So,

No. of favorable outcomes = 0.08 × 6000

No. of favorable outcomes = 480.

Therefore, the girl bought 480 tickets.
