I am thinking what the graph looks like from your reply "Or do you want to generate a bunch of data and try to empirically produce the binomial distribution? If that's the case, just generate a bunch of sets of N ones and zeros randomly, and for each set, count the number of times one appears...

ok .. if use histogram, we will have only 2 bars, one is shorter than another,right?

Because the only difference of these 2 curves is the p which can controls the curve position. So you mean we cannot do so,right? How can I obtain 2 curves that easily to distinguish the H and T clusters??

Ok if I take your approach, randomly generate 1 and 0, and would like to plot the histogram, what is the x-axis? y-axis should be the probability,right? I use Matlab and run the following clear; x1=1:102; y1 = binopdf(x1,102,0.2); x2=1:102; y2 = binopdf(x2,102,0.8)...

hm..yes we don't have the actual sequence according to the question. what is wrong with the question?? The main objective is to plot the graph and see these 2 results (i.e.H or T) has a easy distinguished pattern. If it is the unbiased coin, i.e. p(h)=0.5, the pattern is not easy to distinguish.

sorry the question is already posted. We can make our assumption as long as it is a biased coin. Example: total 26 trials (n+m) and prob. of getting head is 0.8 does it make sense?? The main objective is to show that in biased case, the plotted curve is easily be distinguished by just...

Given a biasd coin and flip 26 times. Example: HHHTTTHHHTTTTHHT p(H)=0.8 How to interpret the sequence using Binomial distribution? and How is the graph looks like?

like coins flipping 0=H 1=T p(H)=0.8 p(T)=0.2

sorry my question is unclear objective: plot a binomial distribution curve by giving a sequence of '0' and '1' Example: 00000011100010010100011110 say,p=0.8 q=0.2, N=26

Homework Statement Given a series of 0 and 1 , how can we plot the binomial curve ?? Example: 00000011100010010100011110 say,p=0.8 q=0.2, N=26 Homework Equations If I apply the classic binomial formula, 26C0 (0.8)^0(0.2)^(26-0) etc.. seems cannot do so.

sorry pls correct me if I am wrong. Didn't Einstein say that Gravity is nothing but a geometry curved only? It is NOT a force and we are living in curved space. isn't it? Alex

Thanks! So, the light bending (near Sun) is due to force basically. One more question, do we also suffer from gravitation wave on Earth as well?? Alex

HI, According to GR, gravitation is simply the geometry bending. Does this also apply on Earth? We can stick on Earth, does it the force attract us?? Or is a geometry problem as well?? I get confused about this. Thanks Alex

Thanks and will try it. Alex

sorry for unclear formula. it should be ln{ (1-x) / (1-p) } *I am not familiar with the latex format sorry.. Alex
