Question

Suppose A and B sre mutually exclusive events where P(A) =.01 and P(B)=0.7, then P(AB)=0.8. True or False

Cobinations are distinguishable ordered arrangements of items all of which have been drawn from a given group of items. True or False

Which of the following statements if false?

a. An event that can be decomposed into two is called a simple event.

b. The probability of an event A is equal to the sum of the probabilities of the simple events contained in A. c. The sum of the probabilities for all simple events in the sample space equals 1.

d. The set of all simple events of an experiment is called the sample space.

e. The probability for any event in the sample space is between 0 and 1 inclusive.

Explanation / Answer

1) P(AB) is 0 for mutually exclusive events. False

2) False. Combinations are not ordered

3) a. An event that can be decomposed into two is called a simple event

This statement is False because simple events cannot be divided into smaller events. All other statements are True
