Question

An event E is defined as 'getting a number that is a multiple of '1' on rolling a dice once. The probability of the complement event of E is .

• A. 0
• B. 1
• C. $\frac{1}{2}$
• D. $\frac{2}{3}$
• E. $\frac{1}{4}$

Answer 1

The correct option is A 0

On rolling a dice, the possible outcomes
= {1, 2, 3, 4, 5, 6}.
All of the above numbers are multiples of '1'.

So, on rolling a dice, the probability of getting a number which is a multiple of '1'
$=\frac{6}{6}=1$

So, the probability of the complementary event
$=\frac{0}{6}=0$
