Person no 1 sets every bulb on. Person no 2 sets all even bulbs off. People nos 3 thru 100 don't change this.
So, being even, bulb 64 is off and only the odd bulbs are left illuminated.
no rob.
It will be all the square numbers that are left on as each person up to 100 is turning on or off the factors of that number. For every one that is turned on there will be someone to turn it off as it will be the other side of the divisible factor except for square numbers because the factor is the same number so the same person wouldn't turn it off that turned it on. 64 is a square number (8 x 8) so would still be left on as will 1, 4, 9, 16, 25, 36, 49, 81 and 100.

Mr. Black, Mr. Gray, and Mr. White are fighting in a truel. They each get a gun and take turns shooting at each other until only one person is left. Mr. Black, who hits his shot 1/3 of the time, gets to shoot first. Mr. Gray, who hits his shot 2/3 of the time, gets to shoot next, assuming he is still alive. Mr. White, who hits his shot all the time, shoots next, assuming he is also alive. The cycle repeats. If you are Mr. Black, where should you shoot first for the highest chance of survival?
He's better to shoot in the opposite direction, because mr grey will then shoot at mr white because he is the biggest threat because he hits everytime, so say he kills white, black now has a 50-50 chance of hitting mr grey, if he misses. Mr grey then has a 50-50 shot because he hits 2/3 and his first was successful, if grey misses black then wins because he hits 1 of 3 and has missed his last 2 and so his last will hit

Mr. Black should use his shot to miss both of them.
Start a row with the table - well, it was looking for trouble and started giving it large, wasn't your fault - then wait for the Old Bill to turn up and sort everything out?

Right answer I think but Just because he has missed his last two doesn't mean he will hit this time. Every time he shoots he has a 1 in 3 chance of hitting. He can't shoot Grey because if he hits, White will shoot him dead. If he shoots White then he is left in a duel with Grey and Grey has first shot. If he wastes his shot, he will end up in a duel with either White or Grey and will have the first shot, so that is his best option.

When is a daily riddle not a daily riddle?
or
He should shoot at Mr Gray and hope he misses so Mr Gray gets a shot at Mr White. Then he left in a dual with Mr Gray.
He can't shoot Grey because if he hits, White will shoot him dead. If he shoots White then he is left in a duel with Grey and Grey has first shot. If he wastes his shot, he will end up in a duel with either White or Grey and will have the first shot, so that is his best option.
Rub your hands together until they are 'saw', saw the table in half, put the halves together to make a 'hole', escape through the hole.
