Probability is the likelihood or chance that an event will occur. The probability that the sum of the numbers is 9 is 1/9
What is probability?
Probability is the likelihood or chance that an event will occur. Mathematically;
Probability = expected/total outcome
If a number cube with sides labeled 1-6 is rolled two times, then the total outcome is 36.
The set of outcomes that gives a sum of 9 are:
E = {(3, 6), (6, 3),(4, 5),(5, 4)}
n(E) = 4
Pr (sum is 9) = 4/36 = 1/9
Hence the probability that the sum of the numbers is 9 is 1/9
