Two number cubes are tossed together; one is blue and the other is orange. What is the probability of getting an odd number on the orange cube and a total of five?

1/18

11/18

7/18

4/9

This is the concept of probability and statistics. We are required to find the probability of obtaining an odd number on the orange cube and a total of five.

Here we shall proceed as follows.

This is mutually independent occurrence.

Probability of selecting an odd number in the orange cube is:

3/6=1/2

The probability of obtaining a sum of 5 when the cubes are tossed will be:

For us to obtain a total of 5 the following combinations must be tossed;

(1,4), (4,1), (2,3), (3,2)

Probability of obtaining (1,4) or (4,1) or (2,3) or (3,2) will be:

1/6*1/6=1/36

Probability of obtaining this number will be:

1/36+1/36+1/36+1/36

=1/9

The probability of getting an odd number in the orange cube and a sum of 5 will be:

P (x) = 1/9*1/2=1/18
