Binomial Problems using the TI83
A binomial experiment conditions:
1.
The experiment is repeated a fixed number of times.
Each time we repeat the process
it is called a trail.
2.
There are two possible outcomes for each trial.
The outcomes are classified as a
success or as a failure.
3.
The probability of a success is the same for each trial.
4.
The random variable x, is the total number of successes in the fixed trials.
Notation
n = the number of trials
p = P(S) = probability of a success for a single trial
q = P(F) = probability of a failure for a single trial q = 1
–
p
x = the total number of successes in n trials
Calculation of binomial experiments
There is a table in the appendix that sometimes works for specific values but does not
give us a lot of options.
We will be using our calculator to find probabilities.
