PLEASE HELP!! NO SPAM!!! I'm literally about to have a mental breakdown because i cant figure these questions out

Answer 1

Based on the students who passed, the probability that a random student gets an A in Statistics or Psychology or both is 0.226.

The probability that a random student did not get an A in Psychology is 0.84.

What are the probabilities of getting an A in psychology?

In order to find out the probability that a person got an A in either Statistics, Psychology, or both, the formula is:

= Probability of A in Psychology +  Probability of A in Statistics - ( Probability of A in Psychology and Statistics)

= (80 / 500) + (82 / 500) - ( 49 / 500)

= 0.16 + 0.164 - 0.098

= 0.226

The probability of not getting an A in Psychology is:

= 1 -  Probability of A in Psychology

= 1 - (80 / 500)

= 0.84
