Answer 1

To calculate the probability that a randomly selected can of food will be Rotel, you can use the formula for probability:

\[
P(\text{rotel}) = \frac{\text{number of Rotel cans}}{\text{total number of cans}}
\]

In this case, 39 people brought a can of Rotel and the total number of people (and cans) is 100. Therefore:

### Part 1: As a Fraction
\[
P(\text{rotel}) = \frac{39}{100}
\]

### Part 2: As a Percent
To express this as a percent, multiply the fraction by 100:

\[
P(\text{rotel}) = \frac{39}{100} \times 100\% = 39\%
\]

### Part 3: As a Decimal
To express this as a decimal, simply divide the number of Rotel cans by the total number of cans:

\[
P(\text{rotel}) = \frac{39}{100} = 0.39
\]

### Final Answers
- **P(rotel) as a fraction:** \( \frac{39}{100} \)
- **P(rotel) as a percentage:** \( 39\% \)
- **P(rotel) as a decimal (rounded to the hundredths place):** \( 0.39 \)
