Alice, Bob, Chris, Don, Ed, Frank, Gary, Hank, Irene, Jack, Ken, Lane, Mary, Nancy, Olivia, Pete, Quinn, Ron, Steve, and Tony are candidates in an election to be corporate officers (President, Vice President, and Treasurer.)
How many outcomes can the election have with either Alice or Bob as Vice President?

Best ResponseYou've already chosen the best response.1it similar by permutation, but i think we have to divide it to 2 case, case I : Alice be a president, so the rest is 19P2 case II : Bob be a president, so the rest is 19P2 so, total ways = 2 * 19P2
