Since you have 11 entries, you have 11 possible winners.
For each winner, you have 10 possible second-place finishers.
For each pair first-second place, you have 9 possible 3rd place finishers.
The possibilities are 11×10×9 = 990
Therefore, you have to buy 990 tickets.

Answer:
a) 2
b) 5
c) -1
d) x
Step-by-step explanation:
We know the properties of log function as:
1) log(AB) = log(A) + log(B)
2) 
3) log(aᵇ) = b × log(a)
also,
4) 
Given:
a. y = log₂(2²)
thus, using 3
y = 2log₂(2)
or using 4
y = 2 × 
or
y = 2 × 1 = 2
b. y = log₂(2⁵)
thus, using 3
y = 5 × log₂(2)
or using 4
y = 5 × 
or
y = 5 × 1 = 5
c. y = log₂(2⁻¹)
thus, using 3
y = -1 × log₂(2)
or using 4
y = -1 × 
or
y = -1 × 1 = -1
d. y = log₂(2ˣ)
thus, using 3
y = x × log₂(2)
or using 4
y = x × 
or
y = x × 1 = x
