you select a name at random from a hat that contains 33 freshmen,34 sophomores, 30 juniors, and 28 seniors. what is the probability that the name is a seniors?

sum = 33 + 34 + 30 + 28

answer = 28 / sum

You mean statistics by the way. I replied because I do statics and dynamics. It is just luck I knew the probability question answer.

To find the probability of selecting a senior's name from the hat, we need to calculate the ratio of the number of senior names to the total number of names in the hat.

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%.

To find the probability of selecting a senior's name, we need to know the total number of names in the hat.

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.
