Assume that 69.3% of the student athletes are male, 49.7% of the student athletes prefer basketball, 32.3% prefer football, and the rest prefer track. Zero female athletes prefer football. If a randomly selected student athlete prefers basketball, what is the probability that the student athlete is female?

Question
Assume that 69.3% of the student athletes are male, 49.7% of the student athletes prefer basketball, 32.3% prefer football, and the rest prefer track. Zero female athletes prefer football. If a randomly selected student athlete prefers basketball, what is the probability that the student athlete is female?
Expert Solution
Step 1

Assume,

  • M be the event that the selected student is a man.
  • W be the event that the selected student is a woman.
  • B be the event that the selected student prefers basketball.
  • F be the event that the selected student prefers football.
  • T be the event that the selected student prefers track.
  • The total number of athletes is 100. 

The required probability is conditional probability that the selected student is a woman given that the selected student prefers basketball. It can be written as, PWB.

By using the conditional probability formula, PWB can be given as, PWB=P(WB)P(B).
