The probability the family eats two or fewer meals at home during the week. Suppose that we have a sample space S-E,E E, EEg, E E), where E,Ep.... E denote the sample points. The following probability assignments apply: P(E)-05, B = {E, E, E) a. Find P(A), P(B), and P(C). b.. Find AU B and PAUB). c. Find An B and PIAnB). d. Are events A and C mutually exclusive? e Find B' and P(B).

Explanation / Answer

Here frequency of occurence of events are given. So relative ferquency method will be used.

Following table shows the probabilities to each event:

Event Frequency Probability E1 20 20/50 = 0.4 E2 13 13/50 = 0.26 E3 17 17/50 = 0.34 Total 50 1
