Answer:
C
If x = o then f(0) = 4(2) * 0 = 0
If f(x) = 4(2) 0 - 13
then f(x) = -13 at x = 0
Answer:
![\frac{5}{13}](https://tex.z-dn.net/?f=%5Cfrac%7B5%7D%7B13%7D)
Step-by-step explanation:
Given,
Red marbles = 3,
Green marbles = 10,
So, the total marbles = 3 + 10 = 13,
![\because \text{Probability}=\frac{\text{Favourable outcomes}}{\text{Total outcomes}}](https://tex.z-dn.net/?f=%5Cbecause%20%5Ctext%7BProbability%7D%3D%5Cfrac%7B%5Ctext%7BFavourable%20outcomes%7D%7D%7B%5Ctext%7BTotal%20outcomes%7D%7D)
Since, here replacement is not allowed,
Thus, the probability of getting a green marble and a red marble
= first red and second green + first green second red
![=\frac{3}{13}\times \frac{10}{12}+\frac{10}{13}\times \frac{3}{12}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B3%7D%7B13%7D%5Ctimes%20%5Cfrac%7B10%7D%7B12%7D%2B%5Cfrac%7B10%7D%7B13%7D%5Ctimes%20%5Cfrac%7B3%7D%7B12%7D)
![=2\times \frac{3}{13}\times \frac{10}{12}](https://tex.z-dn.net/?f=%3D2%5Ctimes%20%5Cfrac%7B3%7D%7B13%7D%5Ctimes%20%5Cfrac%7B10%7D%7B12%7D)
![=\frac{30}{78}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B30%7D%7B78%7D)
![=\frac{5}{13}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B5%7D%7B13%7D)
Note : The probability of getting a green marble first and a red marble second
= ![\frac{10}{13}\times \frac{3}{12}](https://tex.z-dn.net/?f=%5Cfrac%7B10%7D%7B13%7D%5Ctimes%20%5Cfrac%7B3%7D%7B12%7D)
![=\frac{30}{156}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B30%7D%7B156%7D)
![=\frac{5}{26}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B5%7D%7B26%7D)
