Question

the probability of winning of a game is x/12 if the probability of losing the game is 1/3 find the value of x
​

Answer 1

P(winning the game) + P(losing the game) = 1
x/12+1/3 = 3x+12/36 = x+4/12 = 1

x+4 = 12
x = 8

Answer 2

Answer:

p(winning)=x/12

p(losing)=1/3

total probabilities=1

x/12+1/3=1

x+4/12=1

x=12-4

x=8
