Question

find the value of x is 2 / 3 is the probability of an event not happening and x divided by 2 is the probability of the event happening

Answer 1

as we know
total possibility of an event = 1
then
possibility of not happening the event + possibility of happening the event = 1
2/3+x/2 = 1
taking LCM
(4+3x)/6 = 1
4+3x=6
3x = 2
x = 2/3
HOPE THIS HELP YOU ☺☺

Answer 2

Answer:

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

Step-by-step explanation:

Given :$\frac{2}{3}$is the probability of an event not happening and x divided by 2 is the probability of the event happening

To Find : Value of x

Solution :

Probability of happening an event = $\frac{2}{3}$

Probability of not happening an event = $\frac{x}{2}$

Since we know that the sum of probability of an event is 1

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

$\frac{4+3x}{6}=1$

$4+3x=6$

$3x=2$

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

Hence The value of $x=\frac{2}{3}$
