Question

If p( winning)=x/12;p(losing)=1/3.find x.

Answer 1

Answer:

hope it helps you

Step-by-step explanation:

We know that P(n)+P(not n) = 1

x/12 + 1/3 = 1

x + 12/3 = 12   [multiplying both side by 12]

x+4=12

x=8

Answer 2

Step-by-step explanation:

$= > sum \: of \: probability = 1 \\ \\ = > \frac{x}{12} + \frac{1}{3} = 1 \\ \\ = > \frac{x + 4}{12} = 1 \\ \\ = > x + 4 = 12 \\ \\ = > x = 8$
