three coins, a half-dollar, quarter, nickel are tossed at the same time. to say that there is an outcome xyz means that the half-dollar, landed x, the quarter landed y, and the nickel landed z. the eight equally likely possibilites can be listed as follows: HHH HHT HTH HTT
THH THT TTH TTT
a) give a verbal description of p(A/B)
c)are the probabilities evaluated in parts (a) and (b) equal?
Can you please provide a definition of events A and B?
Also, in (a) do you mean p(A|B) instead of P(A/B)? That is to say, probability of event A given B has happened?
