Answer:
2 out of 10
Step-by-step explanation:
Simple math
Total voters=v=80
total no. of democrats=d=65
total no. of republicans=r=15
probability of democrats=p1=65/80=0.8125
probability of republicans=p2=15/80=0.1875
probability of a democrat or a republican=p1+p2=0.8125+0.1875=1 <span />
I'm assuming you mean to list the terms of the expression. Those are mn, -2n, and +8. There are 3 terms there.
