Question

There are six computers for student use in the Math Lab. The number of computers available at noon on Monday can be described by the following probability distribution. 1. What is the probability that at least three computers are available?

Answer 1

The probability that at least three computers are available is 0.75.

Step-by-step explanation:

To find the probability that at least three computers are available, we need to add up the probabilities of having three, four, five, and six computers available.

From the probability distribution, we can see that the probabilities for each situation are 0.3, 0.2, 0.15, and 0.1 respectively.

Adding these probabilities gives us 0.3 + 0.2 + 0.15 + 0.1 = 0.75.
