please help me in this question

a) i. ii. iii. A group of friends decided to visit hill station (say H) in their vacations. To reach their destination they can follow two routes. The rst directly connects H to K, whereas the second passes through G. Sometimes because of the weather conditions (snow falling). travelers cannot travel between B and A. If there is a forecast of snow for the next day, one can assume (on the basis of prior information) P(H) = 0.6, P( K) : 0.7, P(G) = 0.4, P(GIK) = 0.5 and HE | GnK) = 0.4. Use the concepts of probability to nd out the probability: That the traveler will be able to reach K from H?' That the traveler will be able to drive from H to K by way of G? 1 Which route should be taken in order to maximize his chance to reach K
