You are given the Information that P(A) - 0.30 and P(B) - 0.40. (a) Do you have enough information to compute P(A or B)? Explain. No. You need to know the value of RA and B). No. You need to know the value of RA) + P(B). O No. You need to know the value of RA) - P(B). Yes. This probability is equal to 0.70. (b) If you know that events A and B are mutually exclusive, do you have enough information to compute P(A or B)? Explain. Yes. P(A and B) = 0, so P(A or B) - P(B)-P(A). Yes. P(A and B) - 0.12, so P(A or B) = P(A) + P(B) - 0.12. No. Knowing the events are mutually exclusive does not provide any extra information. Yes. P(A and B) - 0, so P(A or B) - P(A) + P(B). Need Help?

If a woman is selected at random from the survey population of women, find the following probabilities. (3) Awoman asked for a raise) (b) A woman received raise, given she asked for one) (C) Awoman asked for raise and received raise) Need Help?
