Find the probability

Question

In a study of brand recognition, 1106 consumers knew of Exxon, and 2 did not. Use these results to estimate the probability that a randomly selected consumer will recognize Exxon.

Report the answer as a percent rounded to one decimal place accuracy. You need not enter the "%" symbol.

prob =  %

Answer 1

For probability you need a numerator and a denominator.

The denominator is the total from which you are choosing. In this case 1106 + 2 consumers.

The numerator is the number that satisfy the given condition. In this case 2 that do not recognize Exxon.

P = 2/1108 ≈ 0.2%
