Hi

Let x represent how many of the 300 will probably buy full flavor brand coffee

Question Sets Up the Proportion

  22/100 = x/300    |cross multiply to solve

   100x = 22*300

      x = 22*300/100

      x = 66, how many of the 300 will probably buy full flavor brand coffee

 Of 100 coffee shoppers surveyed 22 bought full flavor brand coffee. 

Of the next 300 coffee shoppers, how many will probably buy full flavor brand coffee.

Binomial Problem with n = 300 and p = 0.22

-----------------------

Expected Number = 0.22*300 = 66
