What is the formula for calculating the probability of event A or event B occurring?

• P(A or B) = P(A) + P(B) - P(A and B)

• P(A or B) = P(A) * P(B)

• P(A or B) = P(A) - P(B)

• P(A or B) = P(A) + P(B) + P(A and B)

How do you calculate the probability of selecting two boys from a group of 35 boys and 50 girls?

• P(both boys) = (35/85) * (34/84) = 1/6

• P(both boys) = (35/85) * (50/84) = 5/12

• P(both boys) = (34/85) * (35/84) = 1/12

• P(both boys) = (35/85) * (34/85) = 1/5
