You randomly choose one hat from 3 green hats, 4 black hats, 2 white hats, 2 red hats, and 1 blue hat. What is the probability of NOT choosing a BLACK hat?

8/12

Step-by-step explanation:

There are 12 possible hats you can choose from so that's the denominator

8 of those hats are not black so that's the numerator

rounds up to about 67%

Step-by-step explanation:

3 + 4 + 2 + 2 + 1 = 12 = total = 100%

12 - 4 (the black hats) = 8

without the black hats = 8/12

8              ?

_      =      _

12           100

12 x 8.333333333333333 = 100

8 x 8.333333333333333 = 66.6666(continued)

Hope this helps!

(f - g)(x) = 5x^3 - 3

step-by-step explanation:

rearrange these functions vertically, with like terms in separate columns:

f(x) = 5x^3 - 2

g(x) =         +1

now subtract, column by column:

(f - g)(x) = 5x^3 - 3

50- 250 is correct i did that one too
