The bag contains,
Red (R) marbles is 9, Green (G) marbles is 7 and Blue (B) marbles is 4,
Total marbles (possible outcome) is,

Let P(R) represent the probablity of picking a red marble,
P(G) represent the probability of picking a green marble and,
P(B) represent the probability of picking a blue marble.
Probability , P, is,


Probablity of drawing a Red marble (R) and then a blue marble (B) without being replaced,
That means once a marble is drawn, the total marbles (possible outcome) reduces as well,

Hence, the best option is G.
Answer:
2^-15 or 1/2^15
Step-by-step explanation:
3*-5 is -15 so that makes it 2^-15
Apply the exponent rule a^-b = 1/a^b
That changes it to 1/2^15
Hope this helped! :)

Answer:
DF=13
Step-by-step explanation:
DE+EF=DF
2x+3+4=3x+4
2x+7=3x+4
7-4=3x-2x
x=3
DF=3x+4
DF=3(3)+4
DF=13
