Question

A girl calculates that the probability of her winning the first prize in a lottery is 0.08. If 6,000 tickets are sold, how many tickets has she bought?

Options

• 40

• 240

• 480

• 750

Answer 1

480

Explanation:

Given, total number of sold tickets = 6000

Let she bought x tickets.

Then, probability of her winning the first prize = `x/6000` = 0.08  ...[Given]

⇒ x = 0.08 × 6000

∴ x = 480

Hence, she bought 480 tickets.
