Hi there The formula of the future value of annuity due is Fv=pmt [(1+r)^(n)-1)÷r]×(1+r) Fv future value? PMT payment 9000 R interest rate 0.04 N time 75−51=24 years So Fv=9,000×((((1+0.04)^(24)−1) ÷(0.04))×(1+0.04)) =365,813.17
You want to draw 2 kings from a 52 card deck. And you do it with replacement. There are 4 kings in a standard deck. The probability of getting one of them is 4/52 on the first draw.
For the second draw the probability is the same. 4/52
The probability for both happening is (4/52)*(4/52) = (1/13)*(1/13) = 1/169 = 0.001597
