A composite sample is taken over a period of time, while a grab sample is a snap shot of what is in your well at the time you take the sample. Homeowner samples are generally grab samples.

There are 4 bags each containing 4 red marbles and 1 green marble If you grab one marble from each bag what is the probability of grabbing at least 2 green marbles?

Let's consider first one bag: The probability to grab one green marble is Pg=1/5 The probability to grab one red marble is Pr=1-Pg=4/5 For the 4 bags, it's a binomial distribution: probability to get k green out of n bags, P(X=k)=nCk pk (1-p)n-k = nCk Pgk Prn-k Now, the probability to grab at least 2 green marbles from 4 bags is 1 - (Probability to get no green marble from 4 bags) - (Probability to get just one green marble from 4 bags) Probability to get no green marble is = 4C0 (4/5)4 = (4/5)4 (n=4, k=0, no green marble from each bag, 4C0 Pr4) Probability to get just one green marble is = 4C1 (1/5) (4/5)3 (n=4, k=1, one green marble from one bag and red marbles from the other ones, 4C1 Pg Pr3) Probability to grab at least 2 green marbles from 4 bags is 1-(4/5)4-4*(1/5)(4/5)3 = 0.1801


How many toothpicks are in a pound?

Well, honey, it really depends on the size and weight of the toothpicks. On average, there are about 800 toothpicks in a pound. But hey, don't go counting them one by one, that's a sure way to drive yourself crazy! Just grab a handful and go floss your teeth or something, life's too short to be counting toothpicks.
