Answer 1

We have to find the probability that voters chosen at random is in the given age group not between 45 and 64 years oldn P(w)=n(A)/n(w)

Here n(A)= voters randomly chosen at age group between 18 to 20 & 21to 24 & 25to34 & 35 to 44 & 65 above

n(A)=96.2

n(w)= total frequency

n(w)=150.8

P(w)=n(A)/n(w)

P(w)=96.2/150.8

P(w)=0.637931

Hence probability that voters randomly selected in the given age group not between 45 to 64 is 0.6379.
