if the probability of winning a race of an athlete is 1/6 less than the twice the probability of losing the race find the probability of winning the race
Let the probability of loosing race be x. probability of winning race = 1/6 - 2x ........(1) probability of winning race + probability of loosing race =1 1/6-2x + x = 1 1/6 - x = 1 1 - 6x/6 =1 1 - 6x = 6 - 6x = 6 - 1 - 6x = 5 x = -5/6 putting the value of x in (1) 1/6 - 2(-5/6) 1/6 + 10/6 11/6

11/6 exceeds more than 1. Is it 2x-1/6?

Sibi answered this
probability of losing + probability of winning = 1 x+2x-1/6 = 1 3x= 1+1/6 3x= 7/6 (LCM) x=7/18 thus probability of winning is 11/18.

let the probability of lossing the game be 2x so the probabilty of winning the game +the propabibilty of lossing it =the answer 2x+1/6 =1/3
