Two events A and B are independent, P(A) = .25 and P(B) = .30 . What...
Let A and B be two independent events. If P(A) = .25, what can you say about P(A | B)? Cannot find it since P(A and B) is not known. Cannot find it since P(B) is not known. Cannot find it since both P(A and B) and P( B) are not known. It is equal to .5. It is equal to .25.
7. If A and B are independent events, then P(A and B) equals a. b. c. P(A) + P(B/A). P(A) x P(B). P(A) +P(B). d. P(A/B) +P(B/A) 8.Which formula represents the probability of the complement of event A? b. 1-P(A) c. P(A d. P(A)-1 9. The simultaneous occurrence of two events is called a. prior probability b. subjective probability c. conditional probability d. joint probability 10. If the probability of an event is 0.3, that means the event has a...
For two events A and B, P(A)=0.4 and P(B)=0.3 (a) If A and B are independent, then P(A|B)= P(A∪B)= P(A∩B)= (b) If A and B are dependent and P(A|B)=0.6, then P(A∩B)= P(B|A) = 2. All that is left in a packet of candy are 8 reds, 2 greens, and 3 blues. (a)What is the probability that a random drawing yields a green followed by a blue assuming that the first candy drawn is put back into the packet?
Suppose two events A and B are two independent events with P(A) > P(B) and P(A U B) = 0.626 and PA กั B) 0.144, determine the values of P(A) and P(B).

Help please! Suppose two events A and B are two independent events with P(A) > P(B) and P(AU B) = 0.626 and PAn B)-0.144, determine the values of P(A) and P(B). 9.
#8. Let A and B be two independent events with P(A)-0.4 and P(A U B)-0.64. What is P(B)?
Suppose the events A and B are independent. Suppose that P (A) =0 .12 and P (B) =0 .07. What is the probability that only event A occurs?
Consider two events A and B. It is known that P(A) = 0.5 and P(B) = 0.9. As well, it is known that A and B are independent. Calculate the following to two decimal places. (a) Calculate the probability of A AND B. (b) Calculate the probability of A OR B. Ž
If A and B are independent events, P(A)=0.11 , and P(B)=0.74 , what is P(B|A) ?
