Question

Math help! Medal :)

Answer 1

Shelly delivers the weekly local paper to neighborhoods in her town. House numbers are even on one side of the street and odd on the other. Shelly delivers an equal number of papers to both sides of the street. Although she always aims for the front doorstep, Shelly typically misses on three of the tosses on her route each week. Design and conduct a simulation to estimate the probability that next week, Shelly's three misses will all be at odd-numbered houses.

Hint: You can set up the experiment using 3 coins to collect the data. Allow one side of the coin to represent Heads (evens) and one other side to represent Tails (odds).

a) Explain clearly your design of the simulation, including choice of probability tool and description of a single trial.
b) Conduct the simulation with twenty trials and record the results.
c) Calculate the experimental probability that all 3 of Shelly's missed papers will be at odd-numbered houses.

Answer 2

How do I do this, step by step?

Answer 3

Answer 4

like they tell you in the hint, it's the same as if you'd flip a coin 3 times, and try to get tails 3 times in a row

Answer 5

But, how do I explain with the a, b, c, d?

Answer 6

a single try is a sequence of 3 coin flips.

20 trails is 20 sequences of 3 coin flips

c is just a calculation

Answer 7

in fact c is the results of the experiment so you don't even need to calculate, but write what you got as a result of your experiment. which will likely be different than the actual odds.

Answer 8

so whats the calculation?

Answer 9

it's more of an experiment than a calculation

Answer 10

see if you can find a coin or a dice nearby and try t for yourself, that's pretty much what they ask

Answer 11

thanks for your help, but i just dont get it.

Answer 12

well, they ask you to simulate the event by using a coin or a dice or any other random number generator.
