1. Suppose that we are going to sample 16 pieces of data from a normal distribution with a mean of 60 and a
standard deviation of 3.5.
a) What is the probability that our data average will be larger than 61.2?
Remember to
Drawing 3 cards and getting 3 Aces (revisited)
Draw 3 cards from a standard deck of cards. Determine
P All 3 Aces
.
When we only own counting techniques, there is only one way to solve the problem:

Number of 3 card hands containing 3 Aces 3
4(3)(2)
In the binomial tables in our book (and Poisson table), the authors have given the distribution in cumulative
distribution function (CDF) format. This is a format that is superior to the probability mass function (pmf) format.
It would have been nice, hum
