Answer:
probability of getting the sum of scores as a prime number = 5/12
Step-by-step explanation:
Two dice are thrown together.
total number of possible events = 6 * 6 = 36
Sum can be from 2 to 12
Prime numbers from 2 to 12 are
2 , 3 , 5 , 7 , 11
Possible Events
(1,1) , (1 , 2) , (2, 1) , ( 1 , 4) , (2 , 3) , (3 ,2) , (4 , 1) , (1 , 6) , (2, 5) , (3 , 4) , (4 , 3) , (5 , 2) , ( 6, 1) , (5 , 6) , ( 6 , 5)
= 15
Probability = 15/36
= 5/12
probability of getting the sum of scores as a prime number = 5/12
