BMST - Basic Math and Science Data Interpretation and Probability Questions and Answers 4

Question 1

A pie chart shows survey results about favorite subjects: Math 30%, Science 25%, English 20%, History 15%, Art 10%. If 200 students were surveyed, how many chose Math or Science?

Accepted Answer

110

Answer

Math (30%) + Science (25%) = 55% of 200 = 0.55 × 200 = 110 students.

Question 2
