If your mom has 200,000 dollars in the bank and you ask her for 300 on monday and and 700 on friday morning and 10.50 on friday night and 1.25 on sunday and she took out 500 to pay the phone bill and the rent. how much money she has remained in the bank

200000 - 300 - 700 - 10.50 - 1.25 - 500 is the amount remaining.

This can be reduced to 198488.25

$198,488.25

200,000 - 300 - 700 - 10.50 - 1.25 - 500 = d

200,000 - 300 = 199,700

199,700 - 700 - 10.50 - 1.25 - 500 = d

199,700 - 700 = 199,000

199,000 - 10.50 -1.25 - 500 = d

199,000 - 10.50 = 198989.50

198989.50 - 1.25 - 500 = d

198989.50 - 1.25 = 198988.25

198988.25 - 500 = d

198988.25 - 500 = 198488.25

so d = 198488.25

she would have $198488.25 in her bank

step-by-step explanation:

conditional probability is defined as:

p(a|b) = p(a∩b) / p(b)

in other words, the probability that a occurs, given that b has occurred = the probability that both a and b occur / the probability that b occurs.

in this example:

p(turns 64 | turns 44) = p(turns 64 & turns 44) / p(turns 44).

if someone turns 64, they must have already turned 44, so:

p(turns 64 | turns 44) = p(turns 64) / p(turns 44)

on page 42, we see that of the original 100,000, 94944 turn 44, and 81234 turn 64.   therefore:

p(turns 64 | turns 44) = 81234 / 94944

p(turns 64 | turns 44) = 0.85560
