sum = 33 + 34 + 30 + 28
answer = 28 / sum
answer = 28 / sum
The total number of names in the hat is given by:
Total = Number of Freshmen + Number of Sophomores + Number of Juniors + Number of Seniors
Total = 33 + 34 + 30 + 28 = 125
The number of senior names is 28.
Therefore, the probability of selecting a senior's name is:
Probability = Number of Seniors / Total
Probability = 28 / 125 ≈ 0.224
So, the probability of selecting a senior's name from the hat is approximately 0.224, or 22.4%.
The total number of names in the hat can be calculated by adding the number of freshmen, sophomores, juniors, and seniors together:
Total number of names = number of freshmen + number of sophomores + number of juniors + number of seniors
Total number of names = 33 + 34 + 30 + 28
Now, we can calculate the probability of selecting a senior's name:
Probability of selecting a senior's name = number of seniors / total number of names
Plugging in the values:
Probability of selecting a senior's name = 28 / (33 + 34 + 30 + 28)
To simplify further, we can add the numbers in the denominator:
Probability of selecting a senior's name = 28 / 125
Therefore, the probability of selecting a senior's name from the hat is 28/125.
