 Only contacts Only glasses Both Neither Total Male 64 841 177 456 1538 Female 189 427 368 681 1665 Total 253 1268 545 1137 3203

(a) The person wears only contacts or only glasses.

(b) The person is male or wears both contacts and glasses.

(c) The person is female or wears neither contacts nor glasses.

(d) The person is male or does not wear glasses.

Step-by-Step Solution:

Solution :

Step 1 of 4:

Given the results of a survey that asked 3203 people whether they wore contacts or glasses.

Then the table is given below,

 Only contacts Only glasses Both Neither Total Male 64 841 177 456 1538 Female 189 427 368 681 1665 Total 253 1268 545 1137 3203

a). We need to find the probability that the person wears only contacts or only glasses.

Then the probability that the person wears only contacts or only glasses is

P(only contacts or only glasses) = P(only contacts)+P(only glasses)

P(only contacts or only glasses) =

P(only contacts or only glasses) =

P(only contacts or only glasses) = 0.2491

Therefore, the probability that the person wears only contacts or only glasses is 0.2491.
