Question

1. A local 4-H club is holding a fundraiser in which they plan to raffle off a side of beef, with 300 tickets available at $10 each. Assuming they sell all their raffle tickets, what is the probability of winning the beef half if you purchased at least four tickets?

2. In horse racing, a trifecta bet is won if you correctly select (in the right order) the horses that finish first, second and third in the race. Assuming there are 15 horses in a race, what is the probability that you would randomly select the three horses that finish first, second and third in the correct order?

Explanation / Answer

1. If 4 tickets are purchased, the probability of winning = 4/300

= 0.0133

2. P(getting 1st, 2nd and third positions in correct order) = 1/15 x 1/14 x 1/13

= 1/2730

= 0.00037
