Explanation:
Mean of a binomial probability distribution is given by np and standard deviation is given by npq, where q=1-p.
In the given example, np=547=207=2.857,
As q=147=37,npq=54737=1760=2157=1.1
Hence mean is 2.857 and standard deviation is 1.107

μ=np
=547
=2.85
σ2=np(1p).
=547(147)
=1.22
σ=σ2=1.22=1.107
