cho đường cạnh ab và hình chiếu đứng d2 của đường thẳng d . Hãy vẽ hình chiếu bằng d1 của đường thẳng d3 biết d đi qua J và cắt AB tại I

binomial distribution

median= 2

range = 7-0 = 7

how to find median?

no. of term=28

median=(28+1)/2=14.5th term

the 14th and 15th term are 2, therefore the median is (2+2)/2 = 2

not only in mathematics, scientific proof also are required in the other field of science. also maths proofs are of particular structure, containing steps and logics. so proving is like doing science, it is science. that's why it is important to prove. 

an inaccurate proof leads to errors, or stating results that are not accurate.  which wil mess the probelm up you dont want this

the answer is two. hope this !
