To simulate the probability in a spinner divide the spinner into colors depending on the probability each color represents.
<h3>What does the word "probability" mean?</h3>
This word refers to the likelihood for an event to occur. Moreover, it is often expressed either as a fraction, a percentage, or a number.
<h3>How to create a spinner to simulate probability?</h3>
In this case, each of the colors represents a probability:
- Green 20%
- Blue 1/4 or 25%
- Yellow 2/5 oe 40%
- Orange 15%
Due to this, the best is to divide the spinner by colors and considering the percentanges of each color. For example 40% of the spinner should be red, while 15% should be orange.

Answer:
The probability that the cost is kept within budget or the campaign will increase sales is 0.88
Step-by-step explanation:
The probability that the cost is kept within budget (event A) <u>or</u> the campaign will increase sales (event B) is the <u>union</u> of the probability of those two events. By basic properties of probability, this is:
P(A ∪ B) = P(A) + P (B) - P(A ∩ B)
and for independent events:
P(A ∩ B) = P(A) * P(B)
So:
P(A ∪ B) = 0.80 + 0.40 - (0.80*0.40) = 1.20 - 0.32 = 0.88
