Question

if p(a)=x/3 and p(ā)=2/3 find x​

Answer 1

Answer:

$\frac{x}{3} + \frac{2}{3} = 1 \\ \\ x + 2 = 3 \\ \\ x = 1$

Answer 2

The value of x is 1.

Step-by-step explanation:

Since we have given that

P(A) = $\dfrac{x}{3}$

and

P(A') = $\dfrac{2}{3}$

As we know that

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

Hence, the value of x is 1.
