Question

Numbers from 1 to 10 are each written on ten separate slips (one number on one slip), kept in a box and mixed well. One slip is randomly chosen from the box. What is the probability of the number chosen being less than 6?

• A. $\frac{1}{3}$
• B. $\frac{1}{2}$
• C. $\frac{2}{3}$
• D. $\frac{4}{3}$

Answer 1

The correct option is B $\frac{1}{2}$

Total number of outcomes = 10
Possible outcomes = 5 (i.e. 1, 2, 3, 4 and 5)
$\therefore$ Probability of the number chosen being less than $6=\frac{5}{10}=\frac{1}{2}$.
