The probability distribution of number of televisions per household in a small town is given below. x 0 1 2 3
P(x) 0.05 0.15 0.25 0.55

a. Find the probability of randomly selecting a household that has one or two televisions.
b. Find probability of randomly selecting a household that has one or two televisions

0.20

Step-by-step explanation:

The given probability distribution of number of televisions per household in a small town:

x          0       1     2      3

P(x) 0.05 0.15 0.25 0.55

To find : The probability of randomly selecting a household that has one or two televisions ( in both parts a. and b.).

The computations for this would be :

P( 1 or 2) = P(1)+P(2)

= 0.05+0.15

= 0.20

Hence, the required probability= 0.20

if you are looking for the unit rate then the answer would be 9 because unit rate is distance divided by time.
