In July in Virginia, the temperature can quickly rise above 90 degrees Fahrenheit, which can also lead to thunderstorms. The probability that the temperature will rise above 90 on a randomly chosen day is 0.68, and the probability of thunderstorms is 0.29. If the temperature rises above 90 degrees, the probability of a thunderstorm is 0.56. What is the probability that the temperature rises above 90 degrees and there is a thunderstorm on a randomly chosen day in July?
0.16
0.20
0.29
0.38
The probability that the temperature rises above 90 degrees and there is a thunderstorm on a randomly chosen day in July = 0.38
So, Option D is correct.
Step-by-step explanation:
The probability that the temperature will rise above 90 on a randomly chosen day = 0.68
The probability of thunderstorms= 0.29
If the temperature rises above 90 degrees, the probability of a thunderstorm = 0.56
We need to find the probability that the temperature rises above 90 degrees and there is a thunderstorm on a randomly chosen day in July?
So, the probability can be found by multiplying the probability that the temperature will rise above 90 on a randomly chosen day with if the temperature rises above 90 degrees, the probability of a thunderstorm
i.e
the probability that the temperature rises above 90 degrees and there is a thunderstorm on a randomly chosen day in July = 0.68 x 0.56 = 0.38
So, Option D is correct.
the 4th choice is the correct one
