A is P(A)=0.5 and the The Probability of event probability of event B is P(B)= 0.3 (Express all answers as decimals; do not include unnecessary decimal places—i.e. answers should be in the form 0.2 or .2 and NOT 0.20, 2/10 or 20%) Find P(A and B) if A and B are disjoint.
An event A will occur with probability 0.5. An event B will occur with probability 0.6. The probability that both A and B will occur is 0.1.The conditional probability of A, given B(a) is 0.5(b) is 0.3(c) is 0.2(d) is 1/6(e) cannot be determined from the information given.We may conclude that(a) events a and B are independent.(b) events A and B are disjoint.(c) either A or B always occurs.(d) events A and B are complementary.(e) none of the above is...
Event A occurs with probability 0.3, and event B occurs with probability 0.4. If A and B are independent, we may concludeA. P(A and B) = 0.12.B. P(A|B) = 0.3.C. P(B|A) = 0.4.D. All of the above
Event A occurs with probability 0.2. Event B occurs with probability 0.8. If A and B are disjoint (mutually exclusive), then(a) P(A and B) = 0.16(b) P(A or B) = 1.0(c) P(A and B) = 1.0(d) P(A or B) = 0.16(e) Both (a) and (b) are true.
Events A and B are independent. Suppose event A occurs with probability 0.32 and event B occurs with probability 0.20. a. If event A or event B occurs, what is the probability that both A and B occur? b. If event A occurs, what is the probability that B does not occur? Round your answers to at least two decimal places. (If necessary, consult a list of formulas.) X 5 ? b. Events A and B are independent. Suppose event...
The probability that the event A occurs is Pr( A ) = 1/3 and the probability that the union event A∪B occurs is Pr( A∪B ) = 5/6. Answer the following questions. 1. If the events A and B are disjoint, what is the value of Pr(B)? 2. If the events A and B are independent, what is the value of Pr(B)? (*Answer in the decimal form, not in the fractional form.) Thank you so much!
