Let A and B be events in a sample space S such that P(A) = 0.33, P(B) = 0.35 and P(A ∩ B) = 0.14. Find P(A | B).
If A and B are events with P(A)=0.4, P(A OR B)=0.52, and P(A AND B)=0.08, find P(B). Provide your answer below:
If A and B are mutually exclusive, with P(A) = 0.33, and P(B) = 0.28, find (a)P(Ac), (b)P(Bc), (c)P(A∪B), (d)P(A∩B), (e)P(Ac∩B), (f)P(Ac|Bc).
Perform the following hypothesis test of a proportion: HO: p = 0.33 HA: p not equal to 0.33 The sample proportion is 0.31 based on a sample size of 100. Use a 10% significance level. A) What is the value of the test statistic? (Give answer rounded to 2 decimals) (be careful to make sure your + or - sign is correct) B) What is the p-value for the problem? C) should the null hypothesis be rejected? YES or NO
A jar contains 4 red marbles numbered 1 to 4 and 7 blue marbles numbered 1 to 7. A marble is drawn at random from the jar. a) Find the probability that the marble is red or odd-numbered. Enter your answer as a percent, rounded to the nearest tenth of a percent. b) Find the probability that the marble is blue, given that the marble is even-numbered. Enter your answer as a percent, rounded to the nearest tenth of a...
Consider the following scenario: . Let P(C) = 0.4 -Let P(D) = 0.5 -Let P(C | D) = 0.6 Part (a) Find P(C AND D). Part (d) Find P(D | C).
Find the area of the triangle ABC. a = 11.6 m b=5.2 m C=13.4° What is the area of the triangle? m2 (Simplify your answer. Type an integer or decimal rounded to the nearest tenth as nee Enter your answer in the answer box.
Consider the following scenario: • Let P(C) = 0.2 • Let P(D) = 0.3 • Let P(C | D) = 0.4 A) FIND P(C AND D)= B)Are C and D mutually exclusive? Why or why not? C and D are mutually exclusive because they have different probabilities. C and D are not mutually exclusive because P(C) + P(D) ≠ 1 There is not enough information to determine if C and D are mutually exclusive. C and D are not mutually...
