5. Help Aunt May in answering some problems about independent events. Consider generating a random three-bit string. Let A be the event that the string contains an odd number of Os, B be the event that the string has exactly one 0, and C be the event that the string starts with 0. a. Are A and B independent? Support your answer. b. Are A and C independent? Support your answer.

a What is meant by the conditional probability of E given F? How is this probability calculated? b What are independent events? c If E and F are independent events, what is the probability of E and F occurring?

Let E be the event the first ball drawn is black and let F be the event the second ball drawn is black. i Find P(EF) if the balls are drawn with replacement. ii Find P(EF) if the balls are drawn without replacement.
Let E and F be events in a sample space S. aThe probability of E and F occurring is P(EF)=______________. bIf the occurrence of E does not affect the probability of the occurrence F, then the events are called ____________.

Let E and F be events in a sample space S. aThe probability of E or F occurring is P(EF)= _________. bIf the events E and F have no outcome in common that is, the intersection of E and F is empty, then the events are called ___________ ____________. So in drawing a card from a deck, the event E, getting a heart, and the event F, getting a spade, are ____________ ___________. cIf E and F are mutually exclusive, then the probability of E or F is P(EF)= _________.
Let E and F be events in a sample space S. (a) The probability of E and F occurring is P(EF)= ______________. (b) If the occurrence of E does not affect the probability of the occurrence F then the event are called ______________. So in tossing a coin twice, the event E ‘getting heads on the first toss,’ and the event F, “getting heads on the second toss,” are _____________ . (c) If E and F are independent events, then the probability of E and F is P(EF)= _____________.
