Question

There are 70 students in a nutrition class. What is the probability that a junior non nutrition major and then a sophomore nutrition major are chosen at random?

Answer 1

0.62% or 1/161

Explanation:

So first you must find the probability that the junior non nutrition major is chosen, this is 10/70. After this the total number of people is lowered down to 69 since one person was chosen. Then you find the probability of a sophomore nutrition major. This is 3/69. Then multiply the two probabilities together. 10/70*3/69 = 1/161 once you reduce it. And if you change it to percentage form it is 0.62%
