Sagot :
Simple math.
Probability is equal to the number of ways it can happen over the total number of outcomes.
Or simple
P = n1 + n2 + n3... / nTotal
However in you question, you have used the word "and" that represent multiplication instead of "or" that represents addition.
So we need to change the formula like this
P = n1 * n2 * n3... / NTotal
So we just need multiply the number of oatmeal to fruits to get nTotal. Since we have two different category.
So we have 3 * 3 = 9 total possibility
And we need to multiply 1 cinnamon oatmeal to 1 raisin fruit
That will be 1
therefore,
P = 1/9
So Amanda can have the probability of having cinnamon with raisin of 1/9 or 0.11.
You can just simply make a table for this.
For oatmeals,
S for brown sugar, M for maple and C for Cinnamon
For fruits,
R for raisins, C for cranberries and B for blueberries

OATMEAL | SR | SC | SB |

| MR | MC | MB |
----------------------------------------------
| CR | CC | CB |
----------------------------------------------
We have a total of 9 outcomes and CR represents cinnamon with raisins.
I hope it helps.
