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!

12

step-by-step explanation:

a triangle's   full angle is 180 degrees so 180 - 156 = 24. 24/2=12

94

step-by-step explanation:

average the numbers and use a variable to figure out the minimum to get a 90.

(79+94+91+92+x)/5=90

x = 94
