no. of ways that each people select a number = 55 no. of ways that each 40 people choose different number = 55P40 probability that each people choose different number = P(A) = 55P40 / 55^40 probability that at least two will choose the same = P'(A) = 1 - ( 55P40) / (55^40)
thanks that was correct
u welcome.....
