From the power rules, the matching of each expression with its equivalent expression is:
<h3>Power Rules</h3>
There are different power rules, see some them:
1. Negative exponent. For this rule when you have a negative exponent, you need to invert the number, i.e, the power base is converted to the denominator. After that, you should solve the power with a positive exponent. See the examples:
2. Power. For this rule, you should repeat the base and multiply the exponents. See the example, .
3. Zero Exponent. When you have an exponent equals to zero, the result must be 1. See the example, .
From this for your question, you have:

Using the binomial distribution, it is found that there is a 0.1111 = 11.11% probability that a certain crate has more than 4 contaminated chickens.
For each chicken, there are only two possible outcomes, either they are contaminated, or they are not. The chickens are independently selected, hence, the binomial distribution is used.
<h3>What is the binomial probability distribution formula?</h3>
The formula is:
The parameters are:
- x is the number of successes.
- n is the number of trials.
- p is the probability of a success on a single trial.
In this problem:
- About 30% of frozen chickens are contaminated, hence .
- Chickens are delivered to grocery stores in crates of 24, hence .
The probability that a certain crate has <u>more than 4 contaminated</u> chickens is:
In which:
Then
Hence
0.1111 = 11.11% probability that a certain crate has more than 4 contaminated chickens.
