Question

a golf ball is selected at random from a golf bag. if the golf bag contains 7 balls of type 1, 4 balls of type 2, and 6 balls of type 3, find the probability of the following event
the golf ball is of type 1 or type 2
the probability that the golf ball is type 1 or type 2 is
(type an integer or a simplified fraction)

Explanation:

Step1: Calculate total number of balls

Total number of balls = \(7 + 4+6=17\)

Step2: Calculate number of favorable balls

Number of type 1 or type 2 balls = \(7 + 4 = 11\)

Step3: Calculate probability

Probability \(P=\frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}}=\frac{11}{17}\)

Answer:

\(\frac{11}{17}\)
