5. Mickey Mouse starts at the left upper-corner vertex and travels to the right lower-corner vertex of the following 8 x 8 grid. He can only walk to the neighboring rightvertex or to the vertex directly below his current position.(a) How many paths can Mickey follow on his journey? (Hint: Any sequence ofeight right or eight down moves will bring Mickey to his destination.)number of paths =(b) Suppose Minnie Mouse is at the circled vertex. What is the probability of theevent E that Mickey stops (by chance) at that vertex and visits Minnie on theway to his destination?P(E)(as a fraction in lowest terms);(as a numerical approximation)5

Answered: (a) How many paths can Mickey follow on…

Make a tree diagram for this question: The probability that a consumer will be exposed to an advertisement for a certain product by seeing a commercial on television is 0.4 The probability that the consumer will be exposed to the product by seeing an advertisement on a billboard is 0.6. The two events, being exposed to the commercial and being exposed to the billboard ad, are assumed to be independent, what is the probability that he or she will be exposed to at least one of the ads?

2. Two friends, David and Peta, often play squash and tennis with each other. Over the years they have found that David wins 3 out of every 5 rounds of squash and 1 out of every 4 tennis matches. If they play one match of squash and then one tennis match: (a) Draw a tree diagram to describe the situation. (b) Find the probability that David wins both matches. (c) Find the probability that Peta wins the second match.
When three athletes compete, the probability of winning the race for the first athlete (A1) is 1/3, the probability for the second athlete (A2) to win the race 1/4, and the probability for the third athlete (A3) to win the race 1/5. Athletes compete 2 times. What is the probability of winning the first race A1 and second race A2, or first race A1 and second race A3?Note: Use the tree diagram. The requested P(A1A2 or A1A3=P(A1A2UA1A3)=P(A1A2)+P(A1A3)

A conditional Probability: P(A | B) is asking what is the probability we get event A if we know that event B occurred. A useful formula: P (A | B) = ||| P(A and B) P(B) Or: P(A | B) = (remaining # of ways to get A) / (remaining number of possible outcomes) A bag has 5 red balls, 7 green balls, and 8 purple balls. Two balls are going to be selected. After the first ball is drawn it is NOT returned to the bag. Find the probability the second is a red ball if you know the first chosen is a red ball. If A = event a red ball is selected: P(A|A) = ?
Suppose that events A and B are mutually exclusive with P(A) = 1 2 and P(B) = 1 6 . (Enter your answers as fractions.) (a) Are A and B independent events? Explain how you know. Since the events are mutually exclusive we know P(A|B) = which P(A) and thus the events are . (b) Are A and B complementary events? Explain how you know. We know that P(A) + P(B) = . And, since P(A) + P(B) 1, the events A and B complementary events.
Philippus flips a fair coin 100 times. Let the outcome be the number of heads that he sees. Philippus now flip his fair coin n times.
