Detailed Solution

Given, a girl calculates that the probability of her winning the first prize in a lottery is 0.08. 6000 tickets are sold.

P (E) = n (E) n (S)

Probability of winning p

(E) = 0.08

Number of tickets sold

= 6000

Find the number of tickets bought.
We know that,

P (E) = n (E) n (S)

Substituting the given values in the above formula,

0 .08 = n (E) 6000

n (E) = 0.08 × 6000

n (E) = 480

The girl bought a total of 480 tickets.
Hence, the correct option 3.
