A bag contains 4 green marbles, 3 blue marbles, and 8 red marbles. What is the probability that you will draw a blue marble when randomly selecting one marble from the bag?
a. 1/4
b. 1/5
c. 2/12
d. 1/3

1/5

Step-by-step explanation:

The total number of marbles in the bag is fifteen, and the total number of blue marbles is 3/15. 3/15 simplified is 1/5.

1/5 is right one

Step-by-step explanation:

P = blue marble / total

=3/15

=1/5

f(x) has value 150 at x= 0

and 0 at x= 3

so d(f(x))/dt = slope = -150/3 = -50

answer: -2+√x,-2-√x

i hope this , i don't know if you're looking for a pair or not.
