Solution
The correct option is B817 For second card = Psamerank(S)+Phigher(H)+Plower(L)=1 PS=13C1×4C252C2=117 ( ∵ selecting one rank out of 13 and then selecting two cards from the same rank) Now PH=PL because there is equal possibility that either the first card has the higher rank and or the second card has higher rank. So 2PH+117=1 PH=817
