following Binomial Distribution problem: “A fair 6-sided die is
rolled six times. Find P(6 comes up at least twice).”
After pressing
p
to input the value of
p
, ClassWiz
automatically converts the fraction into a decimal for its
own purposes.
Press

again to calculate the probability.
To enter the values of
x
(number of successes),
N
(number of
trials), and
p
(probability of success), press
2
