Question

The local golf store sells an onion bag that contains 35 experienced golf balls. Suppose that the bag contains 15 titlesis, 12 maxfils, and 8 filtes. Suppose you select two of the balls at random, without replacement. Answer the following questions reporting your probabilities to four decimals.

What is the probability that the two randomly selected golf balls are both titleists?

What is the probability that the first ball selected is a titleist and the second is a maxfli?

What is the probability that at least one maxfli is selected?

Explanation / Answer

35 golf balls

15 titlesis

12 maxfils

8 filtes

Question 1)

P ( two golf balls are both titlesists) = (15/35) * (14/34) = 0.1765

Answer: 0.1765

Question 2)

P ( first balls titlesis and second is maxfli) = (15/35)*(12/34) = 0.1513

Answer: 0.1513

Question 3)

P ( at least one maxfil) = 1 – P (no maxfil) = 1 – ((23/35)*(22/34)) = 1 - 0.4252 = 0.5748

Answer: 0.5748
