Number of ways the first 4 databases can be selected = 9C4 = 126
Probability that it is in 2 of the first 4 = 5C2 / 126 = 10/126
Probability that it is in 3 of the first 4 = 5C3 / 126 = 10/126
Probability that it is in 4 of the first 4 = 5C4 / 126 = 5/126
Probability that it is in at least 2 of the first 4 = 10/126 + 10/126 + 5/126 = 25/126

Answer:
Step-by-step explanation:
Let the number of month be x
<u>Expression to show amounts</u>
- 2350 + 200x = 3250 + 175x
- 200x - 175x = 3250 - 2350
- 25x = 900
- x = 900/25
- x = 36
<u>Amount</u>
- 2350 + 200*36 = 2350 + 7200 = 9550
Time is 36 months
Amount is $9550
