What are the answers and how do you solve them?
1 Answer
Explanation:
Assuming that (the area, therefore probability of landing is):
Red: 1/2
Blue: 1/4
Green:1/8
Yellow:1/4
3C1 means "ways to choose 1 out of 3". We multiply this because we need to consider all the combinations of two blues and one red we can spin. We need to find "ways 1 out of 3 can be red".
Using the combination formula:
Is this an example of an independent or dependent event?
It is independent, the previous spin does not effect the outcome of the next spin.
