Step-by-step explanation:
Hi!
The sample space of this problems is the set of all the possible sales. It is divided in the disjoint sets:
We have also the set of sales of boat accesories 
, the colored one in the image.
We are given the data:
From these relations you can compute the probabilities of the intersections colored in the image:
You are asked about the conditional probability:
To calculate this, you need 
. In the image you can see that the set is the union of the two disjoint pink and blue sets. Then:
Finally:
This should be the answer and I showed you how to do it

Answer:
The total number of cookies they baked altogether is 216 cookies
Step-by-step explanation:
Here, we want to know the number of cookies that they baked together
From the question, we are told that Clementine baked 72 cookies while Jake baked twice as much
what this mean is that the number of cookies baked by Jake will be (2 * 72) = 144 cookies
Thus, the total number of cookies baked by the two of them will be;
72 + 144 = 216 cookies
The formula is [(l x w) + (w x h) + (h x l)] x 2
Answer:
216 US dollars
Step-by-step explanation:
Let the amount he earned for babysitting be x
He spent 1/4 of x on guitar=(1/4)×x=1/4x
He gave 1/4 of x to charity= (1/4)×x=1/4x
Equation 1
Total amount left=(Total amount earned -Total amount spent)
Total amount earned=x
Total amount spent=(Spent on Guitar+Spent on Charity)=(1/4x)+(1/4x)=1/2x=0.5x
Total amount left=108 US dollars
Substituting in equation 1
108=(x-0,5x)
Solving
0.5x/0.5=108/0.5
x=216 US dollars
He started with 216 US dollars
