Question

An experiment is rolling two dice.
SS = {(1,1), (1,2), (1,3), (1,4), (1,5), (1,6), (2,1), (2,2), (2,3), (2,4), (2,5), (2,6), (3,1), (3,2), (3,3), (3,4), (3,5), (3,6), (4,1), (4,2), (4,3), (4,4), (4,5), (4,6), (5,1), (5,2), (5,3), (5,4), (5,5), (5,6), (6,1), (6,2), (6,3), (6,4), (6,5), (6,6)}

 

a. What is the probability of getting a 1st is 2 or a sum of 7?
P(1st is 2 or sum of 7) =   
Give your answer as a reduced fraction.

 

b. What is the probability of getting a sum of 3?
P(sum of 3) =   
Give your answer as a reduced fraction.

Expert Solution
Step 1

From the provided information,

The total outcome of getting 1st as 2 = 6

The total outcome of getting a sum of 7 = 6

The total outcome of getting 1st as 2 and sum of 7 = 1
