Question

The probability that a student uses the academic resource center on a regular basis is 0.33. in a group of 18 students, what is the probability that exactly 4 of them use the academic resource center on a regular basis?

Answer 1

So here you can make a proportion! .33/18 = x/4 so .33 times 4 = 18x —> (.33 times 4)/18 = x. Plug into calculator to get x

Answer 2

If there's a probability that a student uses the academic resource on an everyday basis is 0.33 the in 18 students the probability that exactly 4 of them uses the resource is 0.073.

What is probability?

The probability is that the likeliness of happening an incident among all the events possible if completed. The formula to calculate the probability is as under:

Probability=number of events/total events.

How to calculate probability?

The probability that a student uses the middle is 0.33.

The probability that 4 students out of the 18 selected=4/18

Then the probability that out of 18, 4 students uses the centre is 4*0.33/18

=1.32/18

=132/1800

=0.073

Hence the probability that 4 students uses the resource is 0.073.
