A bin of 1000 turnbuckles has an unknown number [math]D[/math] of defectives. A sample of 100 turnbuckles has 2 defectives. The maximum likelihood estimate for [math]D[/math] is the number of defectives which gives the highest probability for obtaining the number of defectives observed in the sample. Guess this number [math]D[/math] and then write a computer program to verify your guess.
