Canister vacuums are often rated according to their ease of use, noise level, emissions, cleaning ability, and length of the power cord. The length (in feet) of the electric cord on a canister vacuum is a random variable, X, with a uniform distribution on the interval [20, 30]. Suppose a canister vacuum is selected at random.

The probability that the power cord has a length greater than 26 feet = ?

Solution

the interval given is (20,30)

we have to find the probability of having length bigger then 26 which will have 4 options

hence the probability will be 4/10 = 0.4
