Answer: -11
Step-by-step explanation:
+(-8) can be simplified to -8 because when you multiply a positive sign by a negative sign, the outcome is a negative sign. So your problem is -3-8= and the answer is -11 because when two numbers with the same sign are subtracted/added by each other, the numbers just get added and the sign stays the same. If you're still confused, use a number line. Hope this helps!
So, the full percentage would be 100%.
First, add the two percentages of red and green that has been taken up.
10+20=30
So, subtract that 30% from 100%.
100-30=70
So, the probability of the arrow landing on the green section is 70%.
