To calculate the experimental probability of a student voting for Sam, we first need to find the total number of votes cast in the election.
- Votes for Alex: 20
- Votes for Jordan: 15
- Votes for Sam: 5
Total votes = Votes for Alex + Votes for Jordan + Votes for Sam
Total votes = 20 + 15 + 5 = 40
Now, we can find the probability of a student voting for Sam:
\[ \text{Probability of voting for Sam} = \frac{\text{Votes for Sam}}{\text{Total votes}} \]
\[ \text{Probability of voting for Sam} = \frac{5}{40} = \frac{1}{8} \]
Thus, the experimental probability of a student voting for Sam is:
**A. 1/8**
- Votes for Alex: 20
- Votes for Jordan: 15
- Votes for Sam: 5
Total votes = Votes for Alex + Votes for Jordan + Votes for Sam
Total votes = 20 + 15 + 5 = 40
Now, we can find the probability of a student voting for Sam:
\[ \text{Probability of voting for Sam} = \frac{\text{Votes for Sam}}{\text{Total votes}} \]
\[ \text{Probability of voting for Sam} = \frac{5}{40} = \frac{1}{8} \]
Thus, the experimental probability of a student voting for Sam is:
**A. 1/8**
