a. p(b|a) = p(a and b) / p(a)
b. p(b|a) = p(a) / p(b)
c. p(b|a) = p(b)
d. p(b|a) = p(b) / p(a)

Type the correct answer in the box. use numerals instead of words. if necessary, use / for the fraction bar.a city water tank holds 20 gallons of water. a technician empties 25% of the tank. how many more gallons of water must be removed from thetank so that it has 5 of the water that it started with: the technician must removemore gallons of water for the tank to have 5 of the water that it started with.
