The chance of a white Christmas (defined as at least one inch of snow on the ground) in Spokane is approximately 60%. Run simulations for each of the following.

a) Run a simulation for 10 years and record how many times a white Christmas occurs. Describe and record your results below.
b) Repeat the above simulation 9 more times. Record your results below.
c) Compare your results with the 60% theoretical probability and comment.

anonymous · Answer

Do u get this problem @experimentX ?

experimentx · Answer

you cannot say exactly you will that these numbers of white Christmas. all you have is probability.

anonymous · Answer

so what would I say?

experimentx · Answer

for 1 simulation, you have 60% change that you will have white Christmas.

for 2 simulation, 
 ---  no white christmas  = 64%
---- 1 white christmas = ??
---- 2 white christmas  = 36%

experimentx · Answer

how many white Christmas do you want in 10 years? http://www.mathwords.com/b/binomial_probability_formula.htm

anonymous · Answer

hmm

anonymous · Answer

So no white christmas is 64%, 2 white christmas is 36%, what about 1 white christmas and the rest? i am a little confused

experimentx · Answer

read a bit about Bernoulli's trials http://en.wikipedia.org/wiki/Bernoulli_trial this is like saying that if you toss coin 10 times, how many times do you get heads up. there are all possibilities ... i must say the question is incomplete. In which level do you study BTW?

anonymous · Answer

ok and what do u mean?

experimentx · Answer

there are all possibilities, you cannot say for certain that there will be 8 white Christmas or 7 ..
although you can calculate the percentage of it.

anonymous · Answer

Okay do you think thats what they want me to do? get the percentages

experimentx · Answer

no ... 
do you know about Bernoulli's trials?

anonymous · Answer

no

experimentx · Answer

do you know the combination formula $ \huge  \binom{n}{r} $

anonymous · Answer

no sry

experimentx · Answer

is it computer related question?

anonymous · Answer

Yes

experimentx · Answer

oh!! you should have said it ... do you know any programming?

anonymous · Answer

No I don't, but sorry about that!

anonymous · Answer

So how do i go about this question?

experimentx · Answer

this is computer Question, you should write a program to simulate that.

anonymous · Answer

how

experimentx · Answer

write a code for it http://jsfiddle.net/kCdbf/

anonymous · Answer

Ok im there

anonymous · Answer

did u get my response

anonymous · Answer

?

experimentx · Answer

http://jsfiddle.net/kCdbf/1/

experimentx · Answer

run that piece of code 10 times, and note it

anonymous · Answer

not sure how

experimentx · Answer

when you open up this link you will get a message box, where it simulates a code and you write down the answer http://jsfiddle.net/kCdbf/3/
