We have been given that there are 125 people and three door prizes.
In the first part we need to figure out how many ways can three door prizes of $50 each be distributed?
Since there are total 125 people and there are three identical door prices, therefore, we need to use combinations for this part.
Hence, the required number of ways are:
In the next part, we need to figure out how many ways can door prizes of $5,000, $500 and $50 be distributed?
Since we have total 125 people and there are three prices of different values, therefore, the required number of ways can be figured out by using permutations.

Given: The height of female giraffe = 4.3 meters
The height of male giraffe = 5.5 meters
Let y be the difference in the heights of female giraffe and male giraffe.
The equation to find the difference in the heights=
Therefore, the difference in the heights y =1.2 meters
Hence, the difference in the heights of female giraffe and male giraffe is 1.2 meters.
