Question

In a class of 26 students, 15 of them like maths, 13 of them like English and 9 of them don't like Maths or English. Find the probability that a student chosen at random likes English but not Maths

Answer 1

Answer: 0 0769

Step-by-step explanation:

Let x be the number of students that offer both subjects

15 - x + x + 13 - x + 9 = 26

-x + 37 = 26

-x = -11

x = 11

Number of student that offer english but not math = 13 - 11 = 2

The probability of english but not math = 2/26 = 0.0769
