Question

1. Events A and B are mutually exclusive. P(A) = 0.3; P(B) = 0.2. What is the probability that either A or B will occur? 2. Two kids play a simple game: one thinks of a two-digit number, the other tries to guess the number in 3 attempts. What is the probability that the first student thinks of a number between 20 and 29 (including 20 and 29)? 3. The table below shows the number of students from different departments in the college students union. If you were to calculate the probability that a randomly selected student is from finance dept, which type / approach of probability would you use? Accounting = 10 Finance = 5 Economics = 3 Management = 6 Marketing = 10 Select one: a. subjective b. empirical c. 17.4 d. 0.289 e. classical f. 0.174 g. 0.147 h. 14.7 4. The table below shows the number of students from different departments in the college students union. If you randomly select 1 student, what is the probability that he/she is from finance dept? Accounting = 10 Finance = 5 Economics = 3 Management = 6 Marketing = 10 Answer:? 5.Survey of firms shows their revenue: Under $1 million --- 102 firms $1 million to under $20 million --- 61 firms $20 million to under $50 million --- 37 firms over $50 million --- 10 What is the probability of randomly selecting a firm with revenue under $20 million? 6.Events A and B are mutually exclusive. P(A) = 0.35; P(B) = 0.25. What is the probability that neither A nor B will occur?

          1. Events A and B are mutually exclusive. P(A) = 0.3; P(B) = 0.2. What is the probability that either A or B will occur? 



2. Two kids play a simple game: one thinks of a two-digit number, the other tries to guess the number in 3 attempts.

What is the probability that the first student thinks of a number between 20 and 29 (including 20 and 29)?



3. The table below shows the number of students from different departments in the college students union.

Answer:?

5.Survey of firms shows their revenue:

Under $1 million --- 102 firms

$1 million to under $20 million --- 61 firms

$20 million to under $50 million --- 37 firms

over $50 million --- 10

What is the probability of randomly selecting a firm with revenue under $20 million?

6.Events A and B are mutually exclusive. P(A) = 0.35; P(B) = 0.25. What is the probability that neither A nor B will occur?
