straight vs. flush draw

[jaydoggie]

im holding A8c on the button in no limit tournament.

flop
7h 9h 6s

someone bets minimum and it calls around.

turn
7h 9h 6s (10d)

checks around to me, i move all in.

one person calls with Q5h.

i ran these cards through 2dimes.net and its saying the Q5 is a 50% favorite. can someone explain to me how the Q5 is the favored hand in this situation or give me the actual odds of him rivering me like he does every time >:\
