1. Use the random variable notation to express symbolically each of the following:
The probability that the number of pets owned by a random household is
exactly 2.
The probability that the number of pets owned by a random household is
exactly 4 is equal to 0.16.
An event in which the number of
owned by a random household is
exactly 1.
2. Use the above probability distribution table to find the following:
a. Р(2 < X < 3) —
(Round the answer to 2 decimals)
b. H(5 < X < 6) =
(Round the answer to 2 decimals)
с. Р(X > 0) —
(Round the answer to 2 decimals)
