Question

A number cube is tossed and a spinner is spun. What is the probability of getting a 3 or 4 on the number cube and not getting 8 on the spinner?

Answer 1

P = 0.2917

Explanation:

There are 6 possible results for the cube numbered {1, 2, 3, 4, 5, 6}

There are 8 possible results for the spinner.

Then the amount of results that can be obtained from the combination of these experiments is:

`S = 6 * 8 = 48` possible outcomes.

Then, we seek to obtain a 3 or a 4 and in the spinner any number other than 8.

exist

`S = 2 * 7 = 14` possible ways to obtain this result.

Then the probability sought is:

`P = (14)/(48)\\\\P = 0.2917`

Answer 2

7/24

Explanation:

Given in the question,

a number cube is tossed and a spinner is spun.

Cube have 6 in numbers

1 2 3 4 5 6

probability of having 3 or 4 = 2/6

= 1/3

Spinners are commonly made with 6, 8, 10 and 12 flat surfaces.

If a spinner has 8 flats then you have a 7/8 chance of not getting an 8.

Probability of getting a 3 or 4 on the number cube and not getting 8

"and" mean multiplication

7/8 x 1/3

7/24
