im so confused-

Of the two lights on Dexter Street, the probability of the lights being red is 20% for the first light and 30% for the second light. If a car is driving down Dexter Street, what is the probability that it does not get stopped at either light?

Respuesta :

Just multiply the sum of the light

The probability that it does not get stopped at either light is 14/25.

We have given

Of the two lights on Dexter Street, the probability of the lights being red is 20% for the first light and 30% for the second light.

What is the formula for probability?

The probability of an event A is defined as the ratio of the number of favorable events that occurred in A /total number of events in a sample space

Red light for the first:

The Probability of the red light is 20 out of 100 so you would just find the difference which is 80%.

80/100

Red light for the second:

The Probability of the second red light is 30 out of 100 so you would just find the difference which is 70%.

70/100

The probability of not being stopped at either, multiply across and reduce.

[tex]80/100 * 70/100= 14/25[/tex]

Therefore, The probability that it does not get stopped at either light is 14/25.
