Chapter 39: Q 5 Exercise (page 1136)

Make a table in which you list all possible outcomes of rolling two dice. Call the dice A and B. What is the probability of rolling

(a) a 7,

(b) any double, and

(c) a 6 or an 8?

You can give the probabilities as fractions, such as 3/36.

Short Answer

Expert verified

Therefore, the probabilities are:

a)p=16b)p=16c)p=518 

Step by step solution

01

Given information

Two dice are rolled. Call the dice A and B.

Explanation

The table of all possible outcomes when two dice are rolled:

Explanation

There are a total of 6 dice combinations, with a result of 7. As a result, the probability is:

p=636p=16

Because there are 6 possible double combinations, the probability is

p=636p=16

There are five combinations in which 6 is possible, and five combinations in which 8 is plausible, hence a total of ten possibilities. As a result, probability is:

p=1036p=518
