Question

At a convention, Jim and his three friends each bought three raffle tickets. At the time of the drawing, 400 tickets had been sold. What is the probability that either Jim or one of his friends will win?

A) 1/16
B) 1/4
C) 1/8
D) 1/2

Answer 1

The probability that either Jim or one of his friends will win is 1/33.

Step-by-step explanation:

To find the probability that either Jim or one of his friends will win, we need to calculate the total number of tickets purchased by Jim and his friends and divide it by the total number of tickets sold. Since Jim and each of his three friends bought three tickets, the total number of tickets purchased by them is 4 (Jim + 3 friends) multiplied by 3 (tickets per person) which equals 12 tickets. The probability is then 12 divided by 400, which simplifies to 1/33.
