Question

Please answer the questions clearly

1. Roll a pair of dice, one red and one green. Now, define the following events: A is the event that at least one of the dice will be an even number B is the event that the sum of the die will be equal to 7; C is the event that at least one of the dice is equal to 1 (a) Draw a picture of the sample space. (b) List all the outcomes for each of the events A, B and C explicitly. (c) Highlight/label each of the events on your picture of the sample space. (If you feel it is necessary, you may draw a new picture for each event.) d) Find P(A), P(B), and P(C) (e) Are events A and C independent? Explain using appropriate probabilities and/or theo- (f) Are events B and C disjoint (mutually exclusive)? Explain using appropriate probabilities (g) What is the relationship between P(A) and P(B)? Fill in the blank with one of the following rems? and/or theorems? symbols: s,2P(A) P(B) Explain using appropriate theorems and/or definitions why this makes sense.

Sample Space

Total 36 Outcomes

1 23456123456-23456123456-23456123456

b)

Event A: Total Combinations: 18+9 = 27

123456123456123456246246246 222222444444666666111333555

Event B: Possible Combinations: 6

Red Green Sum 4 4

Event C: Possible Combinations: 11

Red Green 1 1 1 1 2 4 1 2 4

d)

Probability = Favourable Outcomes/Total Outcomes

P(A) = 27/36 = 0.75

P(B) = 6/36 = 0.16667

P(C) = 11/36 = 0.3056

e)

No A and C events are not independent as there are some elements common to both the events.

Independent Events do not have any elements common.

g)

P(A) > P(B)

Hint: Consider A, to be the event that the ith dice shows a "2" for i 1,2,3. We want to find P(A1 UA2U A3) using PI.E. for 3 events. You can assume that each dice is fair, that is, P(A) 1/6, P(Ai n A) 1/6x 1/6-1/36 and P(An A2nA3) (1/6)3 1/216. For an easier solution, consider the complement...
