a survey conducted . According to the survey 37% of adults are concerned that employers are monitoring their calls. Use the binomial distribution formula to calculate the probabilty that
a) out of 5 adults, none is concerned
P(x=0) = 0.63^5 = 0.099
-------------------------------
b) out of 5 adults all are concerned
P(x=5) = 0.37^5 = 0.006934
------------------------------
c) out of 5 adults exactly 3 are concerned
P(x=3) = 5C3(0.37)^3*(0.63)^2 = 0.201042..
