Thread: help me check my answers.

I had this probability problem that I worked out. I did get most of the answers and was wondering if someone could please help me double check the answers and make sure they are correct.

I put my answers in Blue.

The Following Data reflect the attitudes city residents have toward the repealing of the city's sunday blue-law ordinance according to the respondents religious preference.

REPEAL OF BLUE LAW

Religion Disapprove Approve Total
-------------------------------------------------------------------------
Protestant 57 63 120

Catholic 33 17 50

Jewish 10 20 30
--------------------------------------------------------------------------
Total 100 100 200

Give the probabilities for the following possible selections from these data.

a. selecting a catholic. 0.25

b. Selecting a Jewish person who approves of repeal 0.1

c. Selecting a protestant given they approve of repeal 63/200 = 0.315

d. Selecting a protestant and then a catholic with replacement 0.6 and 0.25

e. Selecting a person who disapproves of repeal given they are catholic.0.165
