The probability that a student chosen at random from your class is a psychology major is. 18. What is the probability that a student chosen at random from your class is not a psychology major?

Answer: 0.82

Step-by-step explanation:

We know that:

For any event A, the probability of not getting A is given by : -

P (not A) = 1 - P (A)

Given : The probability that a student chosen at random from your class is a psychology major is P (psychology major) = 0.18.

Then, the probability that a student chosen at random from your class is not a psychology major will be:

P (not psychology major) = 1 - P (psychology major)

= 1-0.18=0.82

Hence, the probability that a student chosen at random from your class is not a psychology major = 0.82
