x0.28 then multiply them and cont the decimal place so when you get the answer you would move the decimal 3 places to the right
Answer: P = 0.75
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:
Answer:
9/34
Step-by-step explanation:
I find when multiplying fractions, its easier to separate them into the numerator and denominator.
So we have 12 x 3, and 17 x 8
12 x 3 = 36
17 x 8 = 136
So we have 36/136
Simplified, that is 9/34
