Answer:
B
Step-by-step explanation:
A is wrong, it increases
C is wrong, the coefficient does not determine if it is linear (straight), the exponent does.
D is wrong, you don't need to know a point to determine if it is linear, (if you have 3 points you can though. )
If the discriminant of a quadratic equation, given by B^2-4AC is positive, it has 2 real solutions. If 0, it has 1 real solution and if negative it has 0 real solutions.

After the 3rd pick we have: 4 white, 3 red and 8 black marbles.
The probability that the 4th marble is black is:
P ( Black ) = 8 / 15 = 0.5333
After the 4th pick we have: 4 white, 3 red and 7 black marbles.
P ( Red or Black ) = 10 / 14 = 5 / 7 = 0.7143
