Question

Spinners Example:

This particular spinner has three colors, but each color is not equally likely to be the result of a spin, since the portions are not the same size.

Since the blue is half of the spinner, P(blue) = 1/2. The red and yellow make up the other half of the spinner and are the same size. Thus, P(red) = P(yellow) = 1/4.

Suppose there are 2 freshmen, 1 sophomore, and one junior in a study group. You want to select one person. The P(F) = 2/4 = 1/2; P(S) = 1/4; and P(J) = 1/4, just like the spinner.

5. What is the probability of rolling a pair of dice and getting one (only one) 6?

Explain how you arrived at your answer.

Explanation / Answer

The discription is different and not at all related to the question.

5. We need to find the probability of getting one six when rolling a pair of dice.

Since each die contains six faces,

Total number of outcomes = 6*6 = 36

Now we need to find total number of outcomes containing one six.

If we consider 6 on the first die then there are 5 possibilities for the second die i.e. from 1 to 5. Similarly, if we consider 6 on the second die then there are 5 possibilities for the first die.

So,

Total outcomes containing 1 six = 5 + 5 = 10

Hence,

P(Getting one six)

= 10/36

= 5/18
