Answer:
5
Step-by-step explanation:
Do the multiplication first: 3 - (-2) becomes 3 + 2.
Thus,
3-(-2) = 5
1/2 is the probability the coin would land heads up both times.
The question we need to ask is what percent of 2 is 40?
40 is 20 times 2 so 20 would be 2,000%
We need to subract 100% from any percent change:
2,000% - 100% = 1,900%
ANSWER: 1,900%
