A bag contains 3 blue marbles, 8 green marbles, and 4 red marbles. One marble is drawn from the bag. What is the probability that the marble drawn is not blue? A. 4/5
B. 4
C. 1/5
D. 1/4​

A.4/5

Step-by-step explanation:

as total outcomes(marbles)=3+8+4=15

P(of getting blue marbles)=3/15

P(not getting blue marbles)= 1-3/15

=(15-3)÷15

=12/15

=4/5

except a rational number. : )

6,250

step-by-step explanation:

to get the area, multiply 360 by 160.(57,600)

to find out how many bags of fertilizer it will take, first figure out how many square feet one bag can hold. divide 1000 by 8(125) to get the unit rate(how many square feet one pound of fertilizer can hold)and multiply it by 50(6250). if i haven't made a mistake, that is the answer.
