Question

13. The probability of getting a job for a person is x/3 . If the probability of not getting the
job is 2/3, then the value of x is
a) 2
b) 1
c) 3
d) 1.5​

Answer 1

Step-by-step explanation:

Probability of not getting job = 2/3

Probability of getting job = 1-2/3 = 1/3

Therefore, x/3 = 1/3

So, x = 1

Hope it helps!!

Thank u

Answer 2

here p(e) =$\frac{x}{3}$

p(not e) = $\frac{2}{3}$

and we know that

p(e) + p(not e ) = 1

$\frac{x}{3}$  + $\frac{2}{3}$ = 1

$\frac{x}{3}$  = 1 - $\frac{2}{3}$

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

$\frac{x}{3}$  = $\frac{1}{3}$

x = $\frac{1}{3}$ × 3

x = 1
