Suppose A and B are events in a sample space with:\[ P(A) = 0.6, \, P(B) = 0.65, \, P(B \cup A) = 0.84 \]Find the following probabilities.\[ P(A \cap B) = 0.41 \]\[ P(B|A) = \, \_\_\_\_ \]\[ P(A|B) = \, \_\_\_\_ \]This image provides information regarding the probabilities of two events, A and B. It specifies the individual probabilities of A and B, the probability of either A or B occurring (union), and the probability of both A and B occurring together (intersection).The conditional probabilities \( P(B|A) \) and \( P(A|B) \) are left to be determined.

An experiment consists of two independent trials. The outcomes of the first trial are A, B, and C, with probabilities of occurring equal to 0.2, 0.4, and 0.4, respectively. The outcomes of the second trial are E and F, with probabilities of occurring equal to 0.7 and 0.3. Draw a tree diagram representing this experiment. Use this tree diagram to find the probabilities below. (a) P(B)(b) P(F | B)(c) P(B F)(d) P(F)(e) Does P(B F) = P(B) · P(F)? YesNo (f) Are B and F independent events? YesNo

A restaurant owner wanted to know which time range are popular among the customers. Data were collected on the following events: L = a customer usually visits the restaurant during lunch time D = a customer usually visits the restaurant during dinner time Data collected suggest the following: P( L ) = 0.6 P( D ) = 0.7 P( L and D) = 0.3 What is the possibility that a customer only visit the restaurant during dinner time
