Binomial problem "P=0.4,n=100P"
i. "P(\\ge44)"
"P(\u226544)=1\u2212P(\u226443)"
From excel Binomial formula; =BINOM.DIST(43,100,0.4,TRUE),"P(\u226443)=0.763469"
Thus,
"P(\u226544)=1\u22120.763469=0.236531"
ii. "P(=44)"
"P(=44)" is given by =BINOM.DIST(44,100,0.4,FALSE) Excel formula, which yields 0.057629547.
Thus,
"P(=44)=0.057629547"
