Answer:
a) 0.167 b)0.056 c)0.023
Step-by-step explanation:
We are given the following information:
Sample space = {(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)}
Total number of outcomes = 36
Formula:
a) P(sum is 7)
Sum 7 possible outcomes = {(1,6), (2,5), (3,4), (4,3), (5,2), (6,1)}
b) P(sum is 11)
Sum 11 possible outcomes = {(5,6), (6,5)}
c) P( sum is 7 or sum is 11)
