Invitations to a party are sent to 100 student.
a) Suppose that for every student, the chance that he or she will attend the party is 40% if it rains and 80% if it does not rain. If the weather forecast says it will rain with a probability of 30%, how many students are expected to show up for the party?
b) Find the probability that at least 70 students show up for the party. If you use approximation methods, state and check the conditions.

$100 is received at the beginning of year 1, $200 is received at the beginning of year 2, and $300 is received at the beginning of year 3. If these cash flows are invested at 12 percent, what will their future value be at the end of year 3?
What is the present value of a $25,000 perpetuity be if the discount rate (required rate of return) is 14 percent? (HINT: Excel does not have a built-in formula for perpetuity. You will need to use the formula for the present value of a perpetuity.)
Bill plans to fund his individual retirement account (IRA) with the maximum contribution of $2,000 at the end of each year for the next 20 years. If Bill expects to earn 12 percent on his contributions, how much will he have at the end of the twentieth year?

Fair Coin? In a series of 100 tosses of a token, the proportion of heads was found to be 0.43. However, the margin of error for the estimate on the proportion of heads in all tosses was too big. Suppose you want an estimate that is in error by no more than 0.05 at the 90% confidence level.
(a) What is the minimum number of tosses required to obtain this type of accuracy? Use the prior sample proportion in your calculation.
You should toss the token at least times.
(b) What is the minimum number of tosses required to obtain this
type of accuracy when you assume no prior knowledge of the sample
proportion?
You should toss the token at least times.
