Probability helps us to know the chances of an event occurring.

The probability that a randomly selected student is a junior will be,
P(Junior) = [(Number of Juniors)\(Number of total students)]

Answer:
3) b = {4 , 9}
Step-by-step explanation:
x^2 + 13x + 36
36 = 9 * 6
13 = 9 + 4
so
x^2 + 13x + 36 = (x + 9)(x + 4) or = (x + 4) (x + 9)
possible b = {4 , 9}
