A probability of 73.7% is displayed.
Because x = 1 was entered, the calculator calculated P(≤ 1 six is
rolled). This provides a great opportunity to use the complement
of an event: P = 1 – 0.737 = 0.263 = 26.3%.
To display the probabilities of obtaining any number of sixes in 6
rolls, press i1(Select Type).
This time, choose 4(Binomial PD).
Because the calculation is for probabilities for several different
numbers of successes, select 1(List).
Enter the values 0, 1, 2, 3, 4, 5, and 6 into the "x" column (which
represents number of successes). Press p after each input.
Once the final value has been entered, press p again to end
the data entry process.
Notice, the values of N and p are preserved from the cumulative
probability calculation.(N and p are global calculator variables.)
