Very Hard Data Analysis And Probability Basic Probability

In a class, there are 5 students: Alice, Bob, Charlie, Dana, and Evan. Each student has participated in different sports during the school year.

The distribution of their participation is as follows:

  • Alice: Soccer, Basketball
  • Bob: Basketball, Baseball, Soccer
  • Charlie: Baseball, Volleyball
  • Dana: Soccer
  • Evan: Basketball, Volleyball

If a student is chosen at random, what is the probability that this student has participated in either Basketball or Soccer?

To find the probability, use the formula:

$$ P(A) = \f\frac{\text{Number of favorable outcomes}}{\text{Total outcomes}} $$
