Suppose the x-axis of a density graph represents someone's height in inches. if the area under the density curve from 60 inches to 70 inches is 0.65, what is the probability of someone's height being anywhere from 60 inches to 70 inches? a. 75% b. 65% c. 60% d. 70%

Option B - 65%

Step-by-step explanation:

Given : Suppose the x-axis of a density graph represents someone's height in inches. If the area under the density curve from 60 inches to 70 inches is 0.65.

To find : What is the probability of someone's height being anywhere from 60 inches to 70 inches?

Solution :

The probability percentage of a curve is defined  as the area under the density curve as

The area under the density curve from 60 inches to 70 inches is 0.65.

So,The probability is equal to the area = 0.65

Therefore, The probability of someone's height being anywhere from 60 inches to 70 inches is 65%.

Hence, Option B is correct.

fist on the left goes with the third on the right. second on the left goes with the fourth on the right. third on the left goes with the second on the right. the fourth on the left goes with first on the right

probability for j is 1/4

while

a is 1/6
