In 2007, 52% of all immigrants to Canada were females, 25% were under 18(adsbygoogle = window.adsbygoogle || []).push({});

years old, and 12% were females under 18 years old.

a. Find the probability that a randomly selected person who immigrated to Canada in

2007 was a female and over 18 years old.

b. Find the probability that a randomly selected person who immigrated to Canada in

2007 was either a female or under 18 years old.

c. Find the probability that a randomly selected person who immigrated to Canada in

2007 was a male and over 18 years old.

d. Are sex and age independent events? Why? (Need a statistical reasoning.)

e. Are sex and age disjoint events? Why? (Need a statistical reasoning.)

I just don't understand the nature of this question, if someone could explain It would be very helpful. So far, I think this is what the questions should look like.

A) 52 + 12 = 64% or (.52 x .12 ) x 100 = 6.24%

B) 52% were females, 25% were under 18 years old so, (.52 x .25) x 100 = 13%

C) 100 - 52 = 48 % was male and the over 18 years old is where i got confused because of the nature of the question.

E) Tryed, but didn't understand.
