Can you tell me if my calculations are right? Thanks.
Three events occur with probabilities P(E1)=0.38, P(E2)=0.14, and P(E3)=0.51. If the event B occurs, the probability becomes P(E1|B)=0.26, P(B)=0.33. Complete parts a through c.
a. Calculate P(E1 and B). ==> 0.38 + 0.26
b. Compute P(E1 or B). 0.38 - 0.33
c. Assume that E1, E2, and E3 are independent events. Calculate P(E1 and E2 and E3). --> 0.38 + 0.14 + 0.51
