Pizza Co. has recently received complaints about the inconsistent amount of cheese on their pizza slices. Michelle, the manager, finds out that the amount of cheese on a slice of pizza is uniformly distributed from 1 to 5 ounces. Find the probability that there is less than 2.5 ounces of cheese on a slice of pizza. Round to 3 decimal places.

Answer:


P( X <2.5) = F(2.5) = (2.5-1)/(5-1) = (1.5)/(4)=0.375

Explanation:

For this case we define the random variable X as "amount of cheese on a slice of pizza" and the distribution for X is given by:


X \sim Unif (a=1, b=5)

We want to find this probability:


P(X <2.5)

And we can use the cumulative distribution function given by:


F(x) = (x-a)/(b-a) , a \leq X \leq b

And for this case we can use this concept and we got:


P( X <2.5) = F(2.5) = (2.5-1)/(5-1) = (1.5)/(4)=0.375
