Possible outcomes = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10}
Total number of outcomes = 10
(1)
Desired outcomes = {6}
Number of desired outcomes = 1
Probability = Number of desired outcomes / Total number or outcomes
= 1/6
(ID)
Desired outcomes = {7, 8, 9, 10}
Number of desired outcomes = 4
Probability = Number of desired outcomes / Total number or outcomes
= 4/10
= 2/5
(II)
Desired outcomes = {1, 2, 3, 4, 5, 6, 7, 8, 9}
Number of desired outcomes = 9
Probability = Number of desired outcomes / Total number or outcomes
=9/10
