The school can expect to raise 1500p for charity.

<u>Explanation:</u>

(a)

The possibility space is solved in the image attached.

(b)

20p for each player

30p for lollipop

Number of people = 120

Charity amount = ?

Out of 12 outcomes, the probability of getting 7 is 3

So, probability of getting 7 for 120 people = \frac{3}{12} X 120

                                                                  = 30

Money earned from the players = 20p X 120

                                                  = 2400p

Cost of 30 lollipops = 30p X 30

                               = 900p

Money received for charity = 2400p - 900p

                                          = 1500p

                                         

Therefore, the school can expect to raise 1500p for charity.
