To find the experimental probability that the first slice sold during lunch tomorrow will be a slice of pepperoni pizza, we can use the formula for probability:
\[
P(\text{event}) = \frac{\text{number of favorable outcomes}}{\text{total number of outcomes}}
\]
In this case:
- The number of favorable outcomes (slices of pepperoni pizza sold) is 20.
- The total number of outcomes (total slices sold) is 76.
Now we can substitute these values into the formula:
\[
P(\text{pepperoni}) = \frac{20}{76}
\]
Next, we can simplify this fraction. Both the numerator and denominator can be divided by 4:
\[
P(\text{pepperoni}) = \frac{20 \div 4}{76 \div 4} = \frac{5}{19}
\]
Thus, the experimental probability that the first slice sold during lunch tomorrow will be a slice of pepperoni pizza is:
\[
P(\text{pepperoni}) = \frac{5}{19}
\]
\[
P(\text{event}) = \frac{\text{number of favorable outcomes}}{\text{total number of outcomes}}
\]
In this case:
- The number of favorable outcomes (slices of pepperoni pizza sold) is 20.
- The total number of outcomes (total slices sold) is 76.
Now we can substitute these values into the formula:
\[
P(\text{pepperoni}) = \frac{20}{76}
\]
Next, we can simplify this fraction. Both the numerator and denominator can be divided by 4:
\[
P(\text{pepperoni}) = \frac{20 \div 4}{76 \div 4} = \frac{5}{19}
\]
Thus, the experimental probability that the first slice sold during lunch tomorrow will be a slice of pepperoni pizza is:
\[
P(\text{pepperoni}) = \frac{5}{19}
\]
