Assume that the weight loss for the first month of a diet program varies between 6 pounds and 12 pounds, and is spread evenly over the range of possibilities, so that there is a uniform distribution. find the probability of the given range of pounds lost. less than 99 pounds

If the distribution is uniform between 6 and 12, the probability of being less than 99 is 1 (certainty).

Perhaps you intend to find the probability that the loss is less than 9 pounds. That value is

... (9 - 6)/(12 - 6) = 3/6 = 1/2

0.5

Step-by-step explanation:

The probability density function for x that uniformly distributed in interval [a,b] :

We assume that the weight loss for the first month of a diet program varies between 6 pounds and 12 pounds and is spread evenly over the range of possibilities, so that there is a uniform distribution.

Let x be the weight loss for the first month of a diet program.

Density function =

Now , the probability of the given range of pounds lost is less than 9 pounds :

Hence, the required probability = 0.5
