Answer 2

Answer:

x = 8/7

Step-by-step explanation:

Here Probability of Happening an Event = 3/7

Probability of not Happening the Event = x/2

We know that

Sum of all Probabilities = 1, therefore

$\frac{3}{7}+\frac{x}{2}=1$

$\frac{x}{2}=1-\frac{3}{7}$

$\frac{x}{2}=\frac{4}{7}$

$x = \frac{8}{7}$
