The Reqd. Prob.#=0.5#.

Let #H=#the Event that a major hurricane hits the city,

#F=#the Event that there is flood in the city.

Then, #HnnF=#the Event that a major hurricane hits the city and

flooding is there in the city.

By the available data, we have,

#P(H)=0.4, P(F)=0.3, &, P(HnnF)=0.2#.

The Reqd. Prob.#=P(F/H)=(P(FnnH))/(P(H))..........[Defn.]#

#=0.2/0.4=0.5#.
