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](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B12%7D%20X%20120)
= 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.
The range is the y values of the function. So it would be (4,5). In order for the relation to be a function, it has to pass the vertical line test. That means that one singular x value cannot equal two different y values. It makes no sense if you really think about it. You can’t plug two different x values into the same function and get the same y value. There’s no repeat in x values, so the relation is a function
