A poll showed that 52.1% of Americans say they believe that statistics teachers know the true meaning of life. What is the probability of randomly selecting someone who does not believe this to be true

0.479

Explanation:

Based on the information given in the question, we can say that:

A = Americans that believe that statistics teachers know the true meaning of life.

B = Americans that do not believe that statistics teachers know the true meaning of life.

P(A) + P(B) = 1

52.1% + P(B) = 1

0.521 + P(B) = 1

P(B) = 1 - 0.521

P(B) = 0.479
