Question

Traffic cameras showed that 15 of every 50 cars passing through a certain intersection did

not fully stop at the stop sign. Based on this sample, what is the probability that a car
arriving at this intersection will not fully stop?
0 0.03
0 0.15
0.30
0 0.50

Answer 1

• 0.30 is the probability that a car arriving at this intersection will not fully stop.

Explanation:

Given that:

• Total number of cars passing = 50 cars
• Number of cars not fully stop at the stop sign = 15 cars

To Find:

• What is the probability that a car arriving at this intersection will not fully stop?

We know that:

• P(E) = F/T

Where,

• P(E) = Probability of an event
• F = Favorable outcomes = 15
• T = Total outcomes = 50

Finding the probability that a car arriving at this intersection will not fully stop:

⟶ P(E) = 15/50

Multiply by 2 with both numerator and denominator.

⟶ P(E) = (15 × 2)/(50 × 2)

⟶ P(E) = 30/100

⟶ P(E) = 0.30

Hence,

• The probability that a car arriving at this intersection will not fully stop is 0.30.

Answer 2

C, 0.30

Explanation:

First, simplify.

`(15)/(50)` =
`(3)/(10)`

Next, divide

3 ÷ 10 = 0.30 or 0.3

Have a great day!
