A researcher is conducting an MTT assay to assess cell viability. They seed 10,000 cells per well in a 96-well plate and treat them with a new drug. After 24 hours, the absorbance at 570 nm is measured for both treated and control (untreated) wells. The results are as follows: Control wells (untreated): Average absorbance = 1.2 AU Drug Treated wells: Average absorbance = 0.6 AU Calculate the percentage of viable cells in the treated wells compared to the

At a local car rental lot there is an employee, Ralph, who returns cars without filling the tank. If the lot has 12 of a specific model of car for rental, and Ralph has returned 5 of them. a.) If we are to randomly select 3 cars what is the probability that At most 1 of the cars requires fuel before it can drive off the lot?           b.) Recalculate the probability above if we know that Ralph only returned 3 cars to the lot.           c.) Suppose now that the probability that any randomly selected car on the lot will need to be filled is 43.58%. If we randomly select 12 cars from the lot (hundreds of cars total) what is the probability that exactly 3 of the cars will need to be filled?
