Question

Please Help. In a box of pink and black candy, there are 5 pink candies for every black piece. design a simulation to estimate the number of pieces a person must choose in order to get 5 peices of black candy.

a. use a spinner with 5 sections, 4 of the sections shaded
b.use a spinner with 11 sections,5 of the sections shaded
c.use a spinner with 11 sections,6 shaded
d.use a spinner with 6 sections,5 shaded

Answer 1

last question I need to finish exam..

Answer 2

the wording of this question is confusing the hell out of me because what i think it really wants is an experiment to show the probability of picking a black candy, not how long one would have to wait to pick five

lets say there are 10 black candies
then there would have to be 50 pink ones, for a total of 60 candies.
the probability of picking a black one would then be \(\frac{1}{6}\) so if your spinner had six sections, 5 shaded, then the unshaded one would have probablity \(\frac{1}{6}\)

Answer 3

seems right these questions confuse the hell out of me too.

Answer 4

so i would go with the last one, but i would not bet the ranch on it
i think the wording of the question belies a deep misunderstanding of probability

Answer 5

but what do i know?
