Hi, you have not provided the distribution, I'll solve the problem for a particular distribution and you can apply the same method for yours.

Answer:

0.39

Step-by-step explanation:

X is the random event and P (X) is the probability of the event X, therefore, X is the number of televisions

Distribution:

X 0 1 2 3 4 5

P (X) 0.24 0.37 0.20 0.11 0.05 0.03

When they ask for the probability of at least Two televisions, they are asking for the probability that the householder has two or more television or P (X>2). To calculate the probability we need to add the probability of each event in the range:

P (X>2) = P (2) + P (3) + P (4) + P (5) = 0.20 + 0.11 + 0.05 + 0.03 = 0.39
