This is a combination problem, as the order in which the 5 people are chosen does not matter.
The number of ways to choose 5 people from a group of 30 can be calculated using the combination formula:
C(n, k) = n! / (k! * (n - k)!)
Where n is the total number of people (30) and k is the number of people to choose (5).
C(30, 5) = 30! / (5! * (30 - 5)!)
C(30, 5) = 142,506
Therefore, there are 142,506 ways to choose 5 people from a staff of 30 to help out at the open day BBQ.

There are 5C30 ways to choose 5 people from a staff of 30 to help out at the open day BBQ.
This can be calculated using the following formula:
nCr = n! / (r! - (n-r)!)
where n is the total number of items, r is the number of items to be chosen, and n! is the factorial of n.
In this case, n = 30 and r = 5, so:
5C30 = 30! / (5! - (30-5)!)
= 30! / (5! - 25!)
= 30 - 29 - 28 - 27 - 26 / 5 - 4 - 3 - 2 - 1
= 142,506
