Alison is learning how to walk. 50% of the time that she takes a step she falls down. Her older brother wants to design a simulation to find the probability she will fall down 5 out of the next 7 times she tries to take step. He sets up a simulation with a flip of a coin where Heads represents falling down and tails represents not falling down. For each trial he flipped the coin 7 times. He did this 19 times and his results are recorded in the table. What is the probability that she falls 5 out of the next 7 times she attempts to take step?
