Question

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?

Answer 1

Answer:C)4/19

Step-by-step explanation:

Answer 2

According to the results of the experiment, the chances of her falling 5 of the next 7 times would be 4/19 or 21.1% chance.  This answer is strictly based on the fact that in his experiment, it happened 4 times out of the 19 times he attempted it.
