total of 50 students 20 girls play lacrosse20 boys play either soccer or lacrosse20 students play soccerwhat is the probability that a student plays soccer or is a girl?

Probability of student playing soccer, P(S) = 20/50 = 0.4
Probability of girls playing lacrosse, P(L) = 20/50 = 0.4

Probability of either playing soccer or being a girl = P(S or L) = P(S)+P(L) = 0.4+0.4 = 0.8
