Question 1026087: A binomial probability experiment is conducted with the
given parameters. Compute the probability of x successes
in the n independent trials of the experiment.
n = 9, p = 0.2, x≤3

You can put this solution on YOUR website! A binomial probability experiment is conducted with the given
parameters. Compute the probability of x successes in the n
independent trials of the experiment.
n = 9, p = 0.2, x≤3
This is the same as this problem:
Suppose a hat contains 10 slips of paper. 2 of the 10 have
x's marked on them and the others are blank. You reach in
the hat and draw one slip at random. You note whether or
not it has an x on it. Put the slip of paper back. Shuffle
them. Draw again and again, each time noting whether you drew
one with an x on it or not, put it back and shuffle. Continue
until you have drawn a slip 9 times. What is the probability
that you drew a slip with an x on it 3 or fewer times?
The answer is 0.9143582724
You did not tell us which method you are to use, table,
formula, or TI calculator. If you want to know how to
do it by any of the three methods, let me know in the
thank-you note form below, and I'll get back to you by
email.
