A IRS auditor randomly selects 3 tax returns from 45 returns of which 15 contain errors. What is the probability that she selects none of those containing errors? Round to four decimal places.
The probability that she selects none of those containing errors is equal to the total number of error-free options divided by the total number of available options. This assumes that each option has an equal chance of being selected.
The probability can be calculated by dividing the number of desired outcomes by the total number of possible outcomes. In this case, the desired outcome is selecting none of the options containing errors and the total number of possible outcomes is the total number of available options.
The probability can be affected by various factors such as the total number of options available, the number of error-free options, and the way in which the options are selected (i.e. randomly or with bias).
Yes, the probability can be affected by the number of errors in the options. If there are more errors in the available options, the probability of selecting none of them containing errors will decrease.
No, the probability cannot be greater than 1. It represents the likelihood of an event occurring and therefore cannot exceed 100%.
