A drawer contains a dozen each of red, blue, green, and white socks, all unmatched. Laura takes socks out at random in the dark.
iren2701 [21]

Answer:

8

Step-by-step explanation:

The probability of picking out a certain colour = 12/48 = 1/4

So, this means that every 4 socks you pick out you can be sure of having one of each colour. If you need to find a pair, then you pick out 8.

Hope this helps

Please help i need help on question b
anzhelika [568]

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
