Answer:
81
Step-by-step explanation:
ANGLES in a TRIANGLE add up to 180
In the Triangle you have 65 and 34
Add them together = 99
Subtract the total from 180
180 - 99 = 81
there are 4 black marbles and totally 7 marbles
p(black marble) =4/7
Odds in favor of black marble = 4:3
<span>Answer: odds 4:3</span>

This is the answer I got:
