1). If a couple has two children, what is the probability that
they are both girls assuming that the older one is a girl?
2). Suppose that we have two dice, the first one being a regular
die, and the second weighted so that half the time it rolls a 1,
and half the time it rolls a 2 (it never rolls anything else). If
we choose one of these dice at random, and roll a 1, what’s the
probability...
In a family of 4 children, what is the probability that two of
the children are boys and two of the children are girls?
answer correct to 4 decimal places
Find the probability that in a family of 4 children there will
bea) At least 1 girlb) At least 1 boy and at least 1 girlc) Out of 1500 families with 3 children each how many would you
expect to have 1 or 2 girls.Assume that the probability of a female birth is 1/2.
Boys and Girls: Suppose a couple plans to have
two children and the probability of having a girl is 0.50.

A married couple has 3 children. What is the probability that
they have 2 boys and one girl? Note: you can assume that for each
birth, p(girl) = 0.5, p(boy) = 0.5.
Helen has two children. Assume that the probability of each
child being a girl is 50%, and is independent with the gender of
the other child. Given that at least one of Helen’s children is a
girl, what is the probability that the other child is a boy?
(A) 1/3 (B) 1/2 (C) 2/3 (D) 3/4 (SHOW WORK)
a) A coin is flipped 6 times, find the probability of
getting exactly 4 heads. Hint: The Binomial Distribution
Table can be very helpful on questions 19-21. If
you use the table for this question, give your answer exactly as it
appears. If you calculated your answer, round to the
thousandths place.
b) A coin is flipped 6 times. Find the probability of getting at
least 3 heads. If you used a table to help find your answer, give
it to the thousandths place....
