Study the binomial distribution table. Notice that the
probability of success on a single trial p ranges from
0.01 to 0.95. Some binomial distribution tables stop at 0.50
because of the symmetry in the table. Let's look for that symmetry.
Consider the section of the table for which n = 5. Look at
the numbers in the columns headed by p = 0.30 and
p = 0.70. Do you detect any similarities? Consider the
following probabilities for a binomial experiment...

3. Submit your answers
to the following binomial questions. You may use the appendix table
B #5 to answer parts (a) and (b). According to a government study,
15% of all children live in a household that has an income below
the poverty level. If a random sample of 15 children is
selected:
a) what is the
probability that 5 or more live in poverty?
b) what is the
probability that 5 live in poverty?
c) what is the
expected...
