Final answer:
To calculate the odds against winning in a lottery with one million tickets sold and one prize, divide the favorable outcomes by the total outcomes. Subtract the probability of winning from 1 to find the odds against winning.
Step-by-step explanation:
To calculate the odds against winning for a lottery with one million tickets sold and one prize, we need to find the probability of winning and then calculate the odds against winning.
The probability of winning is equal to the number of favorable outcomes (1) divided by the total number of outcomes (1,000,000). So, the probability of winning is 1/1,000,000.
To calculate the odds against winning, we subtract the probability of winning from 1. So, the odds against winning are 1 - 1/1,000,000 = 999,999/1,000,000.
