Question

Students choose either biology or botany as the subject for a science project. About 26% choose biology, and about 18% choose botany. What is the probability that a student chosen at random has selected a project in the field of biology or botany?

A 44%
B. 22%
C. 47%
D. 4.7%

Answer 1

Answer: 44%

Explanation:

Let us assume there were 100 students.

Now, 26% means 26 students have chosen biology, and 18% means 18 students have chosen botany.

Now total number of students who have chosen biology or botany = 44

P(the student has chosen biology or botany as subject for project) = 44/100
