Step-by-step explanation:
Here, Total ticket = 2000
According to the question, ticket bought by Neil's group = 10 × 10= 100 ( because there are 10 person in group and each bought 10 tickets)
Therefore, Probability that Neil's group won the prize, P(G) = 100/2,000= 1/20
Now, The probability that Neil and group won,

The relation is not a function.
Step-by-step explanation:
By definition, a relation is a function if each input value has only one output value.
Given the relation:
(4,23)
(3,-2)
(-6,5)
(4,6)
The domain is the set of the x-coordinates of each ordered pair (You do not need to write 4 twice):
{
}
The range is the set of the y-coordinates of each ordered pair :
{
}
Since the input value 4 has two different output values (23 and 6), the relation is not a function.
