Answer: 11/100

Explanation:

There are 11 numbers that are less than 12 from 1-11

Which mean there are 11 possibilities of choosing a number less 12 from the 100 cards.

We can write that probability:

P = 11/100

Therefore, the probability of choosing a number less than 12 in a box of 100 cards is 11/100.

Answer:

D

Step-by-step explanation:

So we have the expression:

(3x^2-5x+6)+(9-8x-4x^2)

Combine like terms:

=(3x^2-4x^2)+(-5x-8x)+(6+9)

Add or subtract:

=(-1x^2)+(-13x)+(15)

Simplify:

=-x^2-13x+15

Our answer is D
