- You can add as many 0's on the end of a decimal and it will still equal the same number, as long as the 0's are on the right side of the decimal point. For example, 0.7 = 0.7000.
- The lowest value has the lowest probability
So, let's rewrite the options with the same amount of decimal points:
1.00
0.90
0.80
0.85
Now, find the value under 0.82. In this option, the lowest value is 0.80, and it is under 0.82, so it is the answer.
Any number multiplied by zero is equal to zero. So if the product is zero, one factor must be zero. Since you already have a nonzero factor, the other must be zero.
