Exam 4: Probability and Probability Distributions

In reviewing retirement portfolios, Kim determined the probability of a client owning stock is 0.70 and the probability of owning a bond is 0.40. The probability of a customer who owns bonds already owning stock is 0.55. What is the probability a client owns both securities in their retirement portfolio?

Question 50

Showing 41 - 50 of 50

A discrete random variable is denoted as distinct countable values x₁, x₂, x₃,…

The Gaussian distribution is the most extensively used probability distribution in statistical work.

Using conditional probability, if P(A) = 0.50, P(B) = 0.20, and P(A $\cap$ B) = 0.15, then P(A | B) =

According to the total probability rule, P(A) equals the sum of P(A $\cap$ B) and P(A $\cap$ B^c), and is considered conditional on two mutually exclusive and exhaustive events independent of an experiment.

If 42% of interns are between the ages of 20 to 25, the complement rule dictates P(A^c) = 1 - P(A) = 1 - 0.42 = 0.58.

Exam 4: Probability and Probability Distributions

A discrete random variable is denoted as distinct countable values x1, x2, x3,…

The Gaussian distribution is the most extensively used probability distribution in statistical work.

Using conditional probability, if P(A) = 0.50, P(B) = 0.20, and P(A ∩\cap∩ B) = 0.15, then P(A | B) =

According to the total probability rule, P(A) equals the sum of P(A ∩\cap∩ B) and P(A ∩\cap∩ Bc), and is considered conditional on two mutually exclusive and exhaustive events independent of an experiment.

If 42% of interns are between the ages of 20 to 25, the complement rule dictates P(Ac) = 1 - P(A) = 1 - 0.42 = 0.58.
