probability that the sum of the two rolls is 7 = 6/15
we were told that the sum of the two dice is a prime, we total up the number of ways this can occur. 1+2+4+6+2=15 ways
The sum could be either a 3, a 5, a 7, or an 11.
3 = (1,2) or (2,1)
5 = (1,4), (4,1), (2,3) or (3,2)
7 = (1,6), (6,1), (2,5), (5,2), (3,4), or (4,3)
11 = (5,6) or (6,5)
Probability defines the likelihood of occurrence of an event. There are many real-life situations in which we may have to predict the outcome of an event. We may be sure or not sure of the results of an event.
P = favorable number of outcomes / total number of possible outcomes.
= (probability that the sum of the two rolls is 7) / (Total pairs having sum prime )
= 6 / 15
