Expert Answer

Mean = np = 3, S. D equals square root of n p q end root equals 3 over 2

q equals fraction numerator S. D squared over denominator n p end fraction equals 3 over 4
p equals 1 fourth n equals 12
Hence, binomial distribution isleft parenthesis p plus q right parenthesis to the power of n equals left parenthesis 1 fourth plus 3 over 4 right parenthesis to the power of 12.
