Step-by-step explanation:
X is defined for all numbers on the domain starting at x=0. It doesn’t show or mention a cutoff/equation in the picture so it’s safe to assume it continues forever
Answer:
C
Step-by-step explanation:
This is a combination question.
In the first instance, we select 5 from 20 and in the second case , we select 4 from 20.
The total number of ways to solve the first instance is 20C5 = 15504 ways
The total number of ways to solve the second instance is 20C4 = 4,845
The ratio of the first to the second scenario is 15,504/4,845 = 3.2 = 16 to 5
4/6 = 1/6 + 1/6 + 1/6 +1/6
