Question

A study has been done to determine to see if the level of education determines how often people move between different states in America. If a person from the survey is randomly selected , what is the probability that they lived in 2 or more states and that they have a college degree? P( 2 state or more U Degree )

0.655

0.111

0.310

0.500

Answer 1

P(2 states or more | college degree)

`$=\frac{\text{P( 2 states or more and college degree)}}{\text{P(college degree)}}$`

Total number of people = 58

The number of people who lived in two states or more than two states and also have a college degree = 18

Therefore,

`$\text{P(2 states or more states and college degree)} = (18)/(58)$`

The number of people who have a college degree = 20

So,
`$\text{P(college degree)} = (20)/(58)$`

Thus,

`$\text{P(2 states or more/college degree)}=((18)/(58))/((20)/(58))$`

`$=(18)/(20)$`

= 0.900
