2. Let the sample space be S= {1,2,3,4,5,6,7,8,9,10}. Suppose the outcomes are equally likely. Compute the probability of the event E= “an odd number less than 8.”

P(E)= ? (type an integer or a decimal. Do not round.)

3. A probability experiment is conducted in which the sample space of the experiment is S= {2,3,4,5,6,7,8,9,10,11,12,13}, event F={4,5,6,7,8}, and event G={8,9,10,11}. Assume that each outcome is likely. List the outcomes in F or G. Find P(F or G) by counting the number of outcomes in F or G. Determine P(F or G) using the general addition rule.

List the outcomes in F or G. Select the correct choice below and, if necessary, fill in the answer box to complete your choice.

MULTIPLE CHOICE

A. F or G= {?}

B. F or G= {}

Find P (F or G) by counting the number of outcomes in F or G.

P(F or G)= ?

(Type an integer or a decimal rounded to three decimal places as needed.)

Determine P (F or G) using the general addition rule. Select the correct choice below and fill in any answer boxes within your choice. (Type the terms of your expression in the same order as they appear in the original expression. Round to three decimal places as needed.)

MULTIPLE CHOICE

A. P (F or G)= ? + ?- ? = ?

B. P (F or G) = ? + ? = ?

4. Find the probability of the indicated event if P(E) = 0.20 and P(F)= 0.40.

Find P(E or F) if P(E and F)= 0.15

P (E or F)= ? (Simplify your answer.)

6. Suppose that events E and F are independent, P(E)= 0.6, and P(F)=0.9. What is the P(E and F)?

The probability P(E and F) is ? (Type an integer or a decimal)

Explanation / Answer

S= {1,2,3,4,5,6,7,8,9,10}.

Odd numbers are {1,3,5,7,9}

only 4 numbers are less than 8

thus probability is 4/10=0.4
