Linda estimates the number of questions she answered correctly on a test. She answered 8 correctly with probability 0.6, 15 correctly with probability 0.3, and 20 correctly with probability 0.1. What is the expected value of the number of questions Linda answered correctly?

Answers

Linda' number of questions has an expected value of 11.3

How to determine the expected value of number of questions?

The given parameters in the question are:

8 questions with probability 0.6,

15 questions with probability 0.3

20 questions with probability 0.1

The expected value is then calculated as

E(x) = Sum of (number of questions * probability)

Substitute the known values in the above equation, so, we have the following representation

E(x) = 8 * 0.6 + 15 * 0.3 + 20 * 0.1

Evaluate

E(x) = 11.3

Hence, the expected value  is 11.3

Students in two classrooms were given a mathematics test. The first classroom had 25 students and their average score was 86%. The second classroom had 15 students and their average score was 94%. If the teacher combined the test scores of students in both classes, what is the average score for both classes?​

Answers

Answer:

Step-by-step explanation:

Total percent in first classroom = 25 x 86 = 2150
Total percent in second classroom = 15 x 94 = 1410
Total for both rooms = 2150 + 1410 = 3560 for 40 students
Average score across both rooms = 3560/40 = 89%
