statistics shows that 40% of South African adults drink coffee, if 6 SA adults are randomly selected, what is the probability that 4 drinks coffee?
Let p be the probability that a randomly selected South African drinks coffee .
Then p= 0.40 .
Let X be the number of SA people out of 6 randopmly selcted , who drinks coffee.
Then X~ Bin( 6 , p=0.40)
and
; x=0,1,2,...,6
SO,
