after ♮many timesε implies that  p=((10)/(25))=(2/5)±0  ⇒ there are ((25)/p)=62.5≈60 candies in the jar

sir why (2/5) ± 0 ?

how sir get 62.5 ?

((25)/(((2/5)))) = ((125)/2) = 62.5 ≈ 60

if we do not know the probability and we  make one test as described here, we get a  normally distributed p. we then have to  define a confidence interval. usually you  want to be at least 95% sure that the  probability lies within [p−ε; p+ε]  you′ll have to study this.  but after ♮many testsε means we are 100%  sure the probability is (2/5). then it′s easy:  we marked 25  if we take out 25 we get 10 marked  we must take out 2.5×25 to get 2.5×10 marked  2.5×25=62.5
