How to describe the random variable?The given parameters are:
Sample size, n = 9Population mean, μ = 5 ouncesStandard deviation, σ = 1 ounceThe mean of the 9 apples is:
μ = 5 ounces * 9
This gives
μ = 45 ounces
The variance of the 9 apples is:
σ² = 1 ounces * 9
This gives
σ² = 9 ounces
Take the square root of both sides, to calculate the standard deviation.
σ = 3 ounces

The probability of the teenager owning a skateboard or a bicycle will be 0.46 or 46%. And the events are mutually exclusive.
What is the addition rule of size for two subsets?For two subsets A and B of the universal set U, we have:
P(A ∪ B) = P(A) + P(B) - P(A ∩ B)
The probability of a new york teenager owning a skateboard is 0.37, of owning a bicycle is 0.36, and of owning both is 0.27.
Then the probability of the teenager owning a skateboard or a bicycle will be
P(A ∪ B) = 0.37 + 0.36 - 0.27
P(A ∪ B) = 0.73 - 0.27
P(A ∪ B) = 0.46
