Answer to relevant QuestionsUse your calculator or computer to find the population variance and population standard deviation for the followingdata.Financial analysts like to use the standard deviation as a measure of risk for a stock. The greater the deviation in a stock price over time, the more risky it is to invest in the stock. However, the average prices of some ...Given P(A) =.10, P(B) =.12, P(C) =.21, P(A ∩ C) =.05 and P(B ∩ C) =.03, solve the following.a. P(A ∪ C) = ______b. P(B ∪ C) = ______c. If A and B are mutually exclusive, P(A ∪ B) = ______Use the values in the joint probability table to solve the equations given.a. P(E ∩ B) =_____b. P(C ∩ F) =_____c. P(E ∩ D)=_____The results of a survey asking, “Do you have a calculator and/or a computer in your home?” follow.Is the variable “calculator” independent of the variable “computer”? Why or whynot?
