Question

In a quiz program, 2 questions on Science, 4 questions on History, and 4 questions on Math are printed separately on 10 cards and placed upside down. Maria is asked to select 2 cards at random. What is the probability of Maria selecting 2 questions on Science

Answer 1

The probability of Maria selecting 2 questions on Science is 1/ 5

How to determine the probability

From the information given, we have that there are;

• 2 Science questions
• 4 History questions
• 4 Math questions

The total questions = 2 + 4 + 4 = 10 questions

We have that Maria picks two questions at random

The probability of her selecting two questions on Science is given as

P(2 science) = number of Science questions/ total number of questions

P(2 science) = 2/ 10

P(2 science) = 1/ 5

The probability of picking two questions on Science is 1/5

Thus, the probability of Maria selecting 2 questions on Science is 1/ 5
