Marlene lives in a building where half the residents live on the first floor and half live on the second floor. She wants to estimate the probability that, out of 3 randomly selected residents, 1 or 2 live on the first floor.
She uses a coin to conduct a simulation, by letting H represent someone living on the first floor and T represent someone living on the second floor and then flipping the coin three times. She repeats this process for a total of 12 trials. The results are shown in this list.
HTT, HHT, HTT, THH,HHT, THT, HTH, THH,HHH, TTH, HHH, TTH
Drag and drop the the simulated probability to the box.
