Question

Which of these is a geometric experiment?


A. Rolling a die 10 times and rolling a one exactly 2 times
B. Flipping a coin 16 times and getting exactly 2 heads
C. Flipping a coin and getting your first tail on the 2nd flip
D. Drawing 1 card from each of 5 different decks of cards and getting 2 clubs

Answer 1

what is meaning of geometric experiment :)

Answer 2

i have no clue..

Answer 3

I confused. don't see the link between the so -called "geometric experiment" with the experiments. that's why I ask you

Answer 4

its on my quiz and im really confused lol

Answer 5

@jim_thompson5910 please, explain us

Answer 6

according to this page

http://en.wikipedia.org/wiki/Geometric_distribution

it's basically used to determine the probability until you reach your first success

Example: you're rolling a die and you want to figure out the probability of rolling a 3 on the first, second, third, etc trials

Answer 7

:) over my head.

Answer 8

so which one??

Answer 9

which one has you looking for the first successful trial

Answer 10

@jim_thompson5910 D?

Answer 11

or a?

Answer 12

no it wouldn't be D because you're not looking for two clubs at a certain trial point

Answer 13

A would be a binomial experiment because there are 2 outcomes per trial and each trial is independent

Answer 14

I think it would be C, but im not really sure.

Answer 15

notice how it says "first tail on the second flip", so that's where you would use the geometric probability distribution

Answer 16

if you wanted to find the probability of getting your first tail on the 10th flip, or the 100th flip, then you would also use the geometric probability distribution

Answer 17

Then what would it be? I have no idea then.

Answer 18

you got it, I was explaining why the answer was that

Answer 19

C would use a geometric distribution

Answer 20

thank you!!
