Question

Mrs. Klein surveyed 240 men and 285 women about their vehicles. Of those surveyed, 155 men and 70 women said they own a red vehicle.

If a person is chosen at random from those surveyed, what is the probability of choosing a woman or a person who does NOT own a red vehicle?

Answer 1

It will be $\frac{300}{525}$ , which is simplified to $\frac{4}{7}$ is the probability of a person who might NOT own a red car.

Answer : $\frac{4}{7}$

Answer 2

Answer:

men who had not have red vehicle=240-155

=85

women..........vehicle=285-70

=215

So;

total ways =240+285

=525

favourable ways =525-225

=300

So; probability= favourable ways/total ways

= 300/525

= 60/105

= 12/21

= 4/7
