Question

Lf n(s)10,n(a)=5 then p(a)=?

Answer 1

Answer:

The probability $P(A)$ is 0.5 .

Step-by-step explanation:

The probability of A can be found using the following formula.

$P(A)= \dfrac{n(A)}{n(S)}$

where $n(S)$ represents the number of elements in the sample space and $n(A)$ is the number of elements in the sample space favoring A.

Given the quantities,

$n(A)= 5\\\\n(S)=10$

Hence the probability is,

$P(A)=\dfrac{5}{10}= \dfrac{1}{2} = 0.5$
