Answer:
0.6 = 60% probability that the bead is RED or GREEN.
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
In this question, we have that:
There are 9 + 8 + 3 = 20 beads.
Of those, 9 + 3 = 12 are red or green.
So, there is a probability that the bead is RED or GREEN.
75 degrees.
All interior angles of a triangle add up to 180.
So we can set up an equation: 65+40+x=180
105+x=180
x=180-105
x=75
11.9
i just got it right on a quiz so yeah
