1 Sampling from discrete distributions
A discrete random variable X is a random variable that has a probability mass function
p(x) = P (X = x) for any x S, where S = cfw_x1 , x2 , ., xk denotes the sample space, and
k is the (possibly innite) number of p

This document will describe how to use R to calculate probabilities associated with common distributions as well as to graph probability distributions.
R has a number of built in functions for calculations involv

Where are we going?
Deer ticks: Are they attracted by deer-gland-substance?
Suppose that 21 out of 30 deer ticks go to the deer-gland-substancetreated rod, while the other 9 go to the control rod.
Would this be a reason
