Answer :
n(s)=150
no of g like t=63....=n(l)
no of g dis like=87...=n(d)
probability for g like t=n(l)/n(s)
=63/150
=21/50
no of g like t=63....=n(l)
no of g dis like=87...=n(d)
probability for g like t=n(l)/n(s)
=63/150
=21/50
Probability that a girl chosen at random likes Tea
= total number of girls liking tea / total number of girls in the survey
= 63 / 150
= 0.42
= total number of girls liking tea / total number of girls in the survey
= 63 / 150
= 0.42
