Question

It is estimated that 52% of drivers text while driving. How many people should a police officer expect to pull over until she finds a driver NOT texting while driving?

Answer 1

To find the number of people a police officer should expect to pull over until she finds a driver not texting while driving, you can use the concept of probability. The formula is Number of people = 1 / Probability of not texting. Therefore, a police officer should expect to pull over approximately 2 people until she finds a driver not texting while driving.

Step-by-step explanation:

To find the number of people a police officer should expect to pull over until she finds a driver not texting while driving, we can use the concept of probability.

Since 52% of drivers text while driving, the probability of a driver texting is 0.52. Therefore, the probability of a driver not texting is 1 - 0.52 = 0.48.

To find the number of people needed to find a driver not texting, we can use the formula:

Number of people = 1 / Probability of not texting

Number of people = 1 / 0.48 ≈ 2.08

Therefore, a police officer should expect to pull over approximately 2 people until she finds a driver not texting while driving.
