Answer / rajkumar
we hav to take two cards from a pack of 52 cards
n(s)=52C2 (ie) 52*51/2*1
= 1326
the event given is the probability that both are queens so that
n(E)= 4C2 (ie) 4*3/2*1
=6
P(E)=n(E)/n(S)
=6/1326
=1/221

Two trains 200 miles apart are traveling toward each other along the same track. Two trains have the same speed 100MPH. A bee is hovering just above the nose of the first train. It buzzes from the first train to the second train, turns around immediately, flies back to the first train, and turns around again. It goes on flying back and forth between the two trains until they collide. If the bee's speed is twice the speed of two trains, how far will it travel?
