Question

Numbers 1 to 10 are written on ten separate slips (one number on one slip), kept in a box and mixed well. One slip is chosen from the box without looking into it. What is the probability of getting a number less than 6?

• A. $\frac{6}{10}$
• B. $\frac{5}{10}$
• C. $\frac{4}{10}$
• D. None of these

Answer 1

Answer: (B)

$\frac{5}{10}$

Since there are $10$ slips. At a time any slip can be drawn once.

$\therefore$ No. of outcomes$10$

Now the numbers less than $6$ are $1,2,3,4,5$ i.e.,$=5$

$\therefore$ Probability of getting a no. less than $6=\frac{5}{10}$
