Since its out of 15 marbles all together and all you need to find is the probability of 3 blue marbles you would have to divide 3 by 15. The outcome would be 0.2 or in your case... B. - 0.20
From the table, we observe that the domain of the function is {Mon, Tues, Wed, Thurs, Fri} and the range is {1, 2, 3, 4, 0}
So, S(Mon) = 1
S(Tues) = 2
S(Wed) = 3
S(Thurs) = 4
S(Fri) = 0
Hence, 
By dividing the area of the polygon with the circles area.
Answer:
1.3
Step-by-step explanation:
I believe this is correct because if you divided 320 by 52 you get 6.15384615385 (or just 6.1) and since we did it to the Y operation we do it to the X operation and x, aka 8, divided by 6.1 equals 1.3.
I'm not 100 percent sure about this, this was very rushed. xx
