Introduction to Probability

Solution

Respondents involved in car accident = 177

Respondents did not involved in car accident = 177

Total Sample = 177+107 = 284

Therefore, the probability of getting someone who has been in a car accident will be:

107/284=0.3767 or there are 37.67% chances that a person picked will be in a car accident.

Solution

108, 128, 138, 108, 158, 208, 148, 128, 118, 168, 118 are the members who have their income greater than $102,000 i.e. n = 11.

Therefore, the probability that a randomly selected member earns at least $102,000 will be:

P (x = 102,000) = 11/20 = 0.55 or ...
