Answer:

Therefore j = 0.9 and k = 1 and after say the p) of not winning =P) b/k when k- b = j as j+b = 1

Explanation:

we are not limited to any one alternative letter so use any alternative letter of alphabet We know each letter represents a decimal where all options of yes or no add up to 1 as they both need to add up to 1 This rule does not apply when the sae letter is told to be represented by a number or given true value or total or part value Usually a given number would need to be taken away fro 1 for winning or loosing questions On the other hand we could get creative and say letters represented place value within an alphabet a=1 b=2 etc = n=1 when n+1 = b and if j = 10 hen k = 11 Then show k-j = 1 = a which also can also be expressed as P) a/k = n/k to show clarity to k = 100% or 1 whole and a/k representing a far lower percentage if relevant to that question of not winning or a negative being lower so really as its higher chance of not winning we na redo and say b = 1/10 /n which proves k-b = 0.9 = j n= k therefore j = 0.9 and after say the p) of not winning = b/k as k- b = j
