Define Binomial distribution
उत्तर
Binomial distribution was discovered by James Bernoulli (1654-1705) in the year 1700.
A random variable X is said to follow binomial distribution with parameters n and p
If it assumes only non-negative value and its probability mass function is given by
`"P"("X" = x) = "p"(x) = {{:(""^"n""C"_x"p"^x"q"^("n" - x) x = 0",", 1"," 2"," ......"n"; "q" =1 -"p"),(0",", "otherwise"):}`
