Discrete Random Variables
... Discrete random variables are obtained by counting and have sample spaces which Are countable. The values that represent each outcome are usually integers. Random variables are denoted by capital letters. ...

Probability of a single event
... What is the probability that my 5 card hand contains at least one heart? (**Use complementary events. Anything other that “no hearts” is “at least one heart”, so you can use 1-P(no ) = P(at least one ) ...

Section 5.6 - Math Heals
... For a fixed p, as the number of trials n in a binomial experiment increases, the probability distribution of the random variable X becomes more nearly symmetric and bell shaped. As a rule of thumb, if np(1-p) > 10, the probability distribution will be approximately symmetric and bell shaped. ...

Combinatorics and Discrete Probability
... A tree can be used to keep track of all the possibilities in a situation. Example: A computer installation has 4 input/output units (A, B, C and D) and 3 CPU’s (X, Y , and Z). How many ways are there to pair an I/O unit with a CPU? • The total number of ways to pair the two types is the same as the ...
