Question

one hundred upper division students attending a career fair at a university were categorized according to class and according to primary career motivation. the table shows the results. if one of these students is to be selected at random, find the probability that the student selected is a senior.

primary career motivation
junior	13	26	0	39
senior	0	13	48	61
total	13	39	48	100

the probability of the student at the fair being a senior is . (simplify your answer. type an integer or a fraction.)

Explanation:

Step1: Identify total number of students

The total number of students is 100.

Step2: Identify number of senior students

The number of senior students is 61.

Step3: Calculate probability

The probability formula is $P(A)=\frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}}$. Here, the favorable outcome is selecting a senior student. So $P(\text{senior})=\frac{61}{100}$.

Answer:

$\frac{61}{100}$
