There are 12 possible outcomes.....three of these will be a "7"  ...so...

 A "7" should occur  1/4 of the time

 

 

If each player pays 20p to play.....the school  will take in  120 * 20  = 2400p

 

However.......1/4 of the players should win =  30 players.....and each lollipop costs 30p.....so......the school should spend 30 * 30  = 900p for the prizes

 

So......the school should raise   2400 - 900 = 1500p  if 120 people play the game

 

 

cool cool cool
