Question

a bucket contains 18 baseballs, 13 softballs, and 9 tennis balls. find the theoretical probability of pulling out a softball. p(sb) = ? round your answer to the nearest hundredth.

Explanation:

Step1: Calculate total number of balls

Total number of balls = \(18 + 13+9=40\)

Step2: Use probability formula

Probability formula \(P(A)=\frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}}\). Here, number of favorable outcomes (softballs) \(n = 13\), total number of outcomes \(N=40\). So \(P(SB)=\frac{13}{40}\)

Step3: Calculate the decimal value

\(\frac{13}{40}=13\div40 = 0.325\approx0.33\)

Answer:

\(0.33\)
