Answer 1

You can express the probability of winning the lottery as a percent (20%), decimal (0.20), or fraction (1/5), as they all represent the same probability.

To express the probability of winning the lottery, you can use any of the options: percent, decimal, or fraction. It doesn't matter which one you choose, as they all represent the same probability.

Let's look at each option:

Percent (20%): This represents 20 out of 100, which is the same as 0.20 or 1/5.

Decimal (0.20): This represents 20 out of 100, which is the same as 20% or 1/5.

Fraction (1/5): This represents the ratio of winning outcomes to all possible outcomes, which is 20 out of 100 or 20%.

Therefore, you can use any of these expressions to communicate the probability of winning the lottery, as they all convey the same information.
