Suppose that A and B are independent events such that P(A) = 0.20 and P(B complement) = 0.70.

3. Find the probability of the intersection of A and B
4. Find the probability of the union of A and B

This solution shows how to calculate the probabilities of the union and intersection of independent events. Two events are considered. The problem gives the probability of A and the probability of the complement of B. From this information plus the knowledge that the events are independent, we can find the probabilities of both the union and intersection of A and B.

"hello, I cannot open the word document" "Thanks a lot for the detailed explanation!
Regards,
Rogel" "One of the best explanations ive seen, thank you much.." "Dear Timothy,
Thank you so much for solving the problem.
I have few questions and I hope you answer them , please.
1) Could you please send me the Excel sheet?
2) In the Correlation Matrix table, how did you get the critical values? or they come with the table by Excel? why is it two tail, and not one tail?
you stated that "The test to evaluate if the slope of the relationship differs significantly from zero has a test statistic value of F = 221.03 and a corresponding p-value of .0000. We can therefore reject the null hypothesis that the slope equals zero and conclude the alternative hypothesis: the slope of the linear relationship differs from zero."
3) So what ? could you please explain more?
4) What is the null hypothesis?
5) What is the alternative hypothesis?
6) Why did you use the ANOVA test? or when you use the Regression Analyze, Excel provides the ANOVA table?
7) Can we use other tests such as t-test to analyze the data? (Yes, No)
8) why did you choose to analyze the data by Regression Analysis?
I Look forward to hearing from you.
Have a great day!
