Question

In throwing a fair die find the probability of the event 'a number less than or equal to 4 turns up'

• A. 2/3
• B. 1/3
• C. 4/5
• D. 1/2

Answer 1

The correct option is A

2/3

In throwing of a single die, there are 6 possible outcomes [1,2,3.......6]

The number of outcomes in which a number $\le$4 turns up are (1,2,3,4)=4

For equally likely events,

$Probability=\frac{numberoffavourableoutcomes}{totalnumberofoutcomes}$

$=\frac{4}{6}$

$\therefore probability=\frac{2}{3}$
