A fair coin is tossed two times, and the events A and B are defined as shown below. Complete parts a through d.
A: {at most one tail is observed}
B: {The number of tails observed is even}
D. Find P(A), P(B), P(AUB), P( Upper A Superscript c Baseline right parenthesis, and P(AnB) by summing the probabilities of the appropriate sample points.
P(A)= ? (Type an integer or simplified fraction.)
Find P(B). P(B)=? (Type an integer or simplified fraction.)
FindP(AuB). P(AuB)=? (Type an integer or simplified fraction.)
Find P(Ac) P(Ac)=? (Type an integer or simplified fraction.)
Find P(AnB). P(AnB)=? (Type an integer or simplifiedfraction.) C.
Find P(AUB) using the additive rule. Compare your answer to the one you obtained in part b.
P(AUB)=? (Type an integer or simplified fraction.)
Compare your answer to the one you obtained in part b. Choose the correct answer below.
A. The value of P(AUB) calculated using the additive rule is less than P(AUB) calculated by summing the probabilities of the sample points.
B. P(AUB) calculated using the additive rule is greater thanP(AUB) calculated by summing the probabilities of the sample points.
C. Both calculations of P(AUB) produce the same result.
E. Are events A and B mutually exclusive? Why?
A. No, events A and B are not mutually exclusive becauseP(AnB)=0.
B. Yes, events A and B are mutually exclusive becauseP(AnB)=0.
C. No, events A and B are not mutually exclusive becauseP(AnB)not equal 0.
D. Yes, events A and B are mutually exclusive becauseP(AnB)not equals0.
According to the rules only first four subparts will be answered. Thankyou
