i)

 

The total number of smokers is 299 and the total number of people is 1,000.

 

That is, n(S) = 299 and n = 1,000.

 

Thus, P(S) = n(S)/n = 299/1,000 = 0.2990.

 

 

ii)

 

The total number of white people is 876 and the total number of people is 1,000.

 

That is, n(W) = 876 and n = 1,000.

 

Thus, P(W) = n(W)/n = 876/1,000 = 0.8760.
