26 red cards +  6 black ( J - Q -K)

32 out of 52 = 8/13

36 possible rolls

  the rolls that are less than 4

     11

      12

        21         3 out of 36      1/12

Each compounding PERIOD is 6 months      2 per year

   interest per period in decimal form is   .10/2 = .05

    12 months is two periods

        10 000 ( 1 + .05)² = amount owed after 1 year = __________  dollars

  Thanx , Chris....I answered this incorrectly the other day....   I edited it after you showed how to calculate it .....( I incorrectly divided the result by 2 )

  .{3/4 * 2   +  1/4 * (-1) ]/2=625 

    I've seen this Q answered by Chris    his answer is :

{3/4 * 2   +  1/4 * (-1) ]= 1.25

largesr base 5     44 ₅ = 24 in base 10

    smallest base 5    01    = 1                 Does Q allow leading zeroes?  I assumed it did

  sum of first 24 numbers =  24/2 (1+24)

24/2(1+24) /24=12.5 avg

If no leading zeroes are allowed in the base 5 numbers     then    10 - 44₅       is      5 - 24 in base 10

290/ 20 = 14.5 avg

450 772 ÷ 14 = 32198 educated folks

One more year of interst will be added in another year

439.23  *  1.10 = ___________ dollars

a1   + a1 + 4      +  a1 +4+4      +a1 +4+4+4       + a1 +4+4+4+4        + a1 +4+4+4+4+4

6a1   + 60 = 150

6a1 = 90

a1 = 15        then  19       23       27    31     35   pies

A={1, 2, 5, 7}​, and B={1, 2, 8}.                    1,2    is the intersection of A and B

a ) 10 * 9 * 8 = 720
