question 10
in a high school graduating class of 298 students, 134 are on the honor roll. of the students who are on the honor roll, 87 are going on to college, and of the other students, 40 are going on to college. a student is selected at random from the graduating class. what is the probability that the chosen student is going on to college?

question 11

Explanation:

Step1: Calculate total number of students going to college

Number of honor - roll students going to college is \(67\). Number of non - honor - roll students going to college is \(40\). So total number of students going to college is \(67 + 40=107\).

Step2: Calculate probability

Total number of students in the graduating class is \(n = 298\). Using the probability formula \(P=\frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}}\), we have \(P=\frac{107}{298}\approx0.36\)

Answer:

\(0.36\)
