Answer:
To get the percecentage of winning can be find out with the help of :
P (x) = numerator+x/denominator+x
so the formula for the case would be:
P(x) = 12+x/25+x
- x = 10 matches
p(x) = (12 + 10)/(25 + 10)
= 22/35
= .6285 or appr 0.63%
- x = 20 matches
p(x) = (12 + 20)/(25 + 20)
= 32/45
= 0.71 or 0.7 appr %
- x = 30 matches
p(x) = (12 + 30)/(25 + 30)
= 42/55
= 0.76 or 0.8 appr %
- x = 50 matches
p(x) = (12 + 50)/(25 + 50)
= 62/75
= .0.8 or 0.9appr %
:- x = 100 matches
p(x) = (12 + 100)/(25 + 100)
= 112/125
= .0.8 or 0.9 appr %
even for the 300 wins, the percentage of winning will be 0.96.
It is now clear that no mater what games they win they can not reach to 100% winning percentage as denominator is higher than the numerator and it is logical if someone already lost 13 games how can be they get 100%
