Abox in a certain supply room contains four 40-w lightbulbs, five 60-w bulbs, and six 75-w bulbs. suppose that three bulbs are randomly selected. a. what is the probability that exactly two of the

The required probability is 0.30.

Step-by-step explanation:

Since we have given that

Number of 40-W lightbulbs = 4

Number of 60-W light bulbs = 5

Number of 75-W light bulbs = 6

Total bulbs = 4+5+6 = 15

We need to find the probability that exactly two of the 75-W light bulbs.

so, it becomes,

Hence, the required probability is 0.30.

2,600 divided by 80 = 32.5

step-by-step explanation:

answer is : muchas/tipicas

have a nice day!
