The data in the following table were obtained in a study to determine the frequency and dependency of IQ ranges relative to males and females. 1,000 people were chosen at random and the following results were recorded:
IQ | ||||
Below 90 | 90-120 | Above 120 | Totals | |
Female | 150 | 300 | 50 | 500 |
Male | 140 | 280 | 80 | 500 |
Totals | 290 | 580 | 130 | 1000 |
5.1 What is the probability of a person having an IQ below 90, given that the person is a female?
5.2 What is the probability of a person having an IQ above 120, given that the person is a male?
