Answer:
a. Probability of landing on red =
b. <em>See Explanation</em>
Step-by-step explanation:
Given
A Spinner
Number of section = 10 (equal sized)
Number of red section = 2
Required
- Probability of landing on red
- Describe the probability in words
Calculating the probability of landing on red
The formula used in calculating probability is as follows
Probability = Number of required outcomes / Number of possible outcomes
In this case, the number of required outcomes is the number of red section.
Hence, number of required outcomes = 2
And the number of possible outcomes is the total section of the spinner
Hence, Number of possible outcomes = 10
By Substitution
Probability of landing on red =
Probability of landing on red =
Describe the probability in words
From (a) above, we have that the probability of the spinner landing on color red is
This means that, for every five times, you spin the spinner, it's likely that one of the outcomes will be red.
