Question

the probability of an event A is 1/3 what is the probability of complement of A

Answer 1

it will be
the formula for getting probability of complement of event =1 - probability of event
1-1/3=3-1/3 = 2/3

Answer 2

Answer:

$\text{Hence}, \text{the probability of complement of A }=\frac{2}{3}$

Step-by-step explanation:

Given that

$\text{The probability of event A }=\frac{1}{3}$

we have to find the probability of complement of A

$P(A)=\frac{1}{3}$

As we know total probability is 1

i.e P(A)+P(A')=1

According to complementary rule

$P(A')=1-P(A)=1-\frac{1}{3}=\frac{2}{3}$

$\text{Hence}, \text{the probability of complement of A }=\frac{2}{3}$
