The probabilities of events A is 0.5
The probabilities of events Bis 0.1
The probability that both A and B occur is 0.20.
P(AorB)=P(A)+P(B)-P(A andB)=0.5+0.1-0.2=0.4.
answer is a.0.4

Use the addition rule for probabilities Question There are two known issues with a certain model of new car. The first issue, A, occurs with a probability of P(A) 0.1. B is another known issue with the car. If it is known that either event occurs witha probability of P(A OR B) 0.93, and that both events occur with a probability of P(A AND B) 0.07, calculate P(B) Provide your answer below: Use the addition rule for probabillities Question If...
