Look at the link below I filled in the answers for you. :)
The chance of student 1's birthday being individual is 365/365 or 100%.
Then the chance of student 2's birthday being different is 364/365.
Then it's narrowed down to 363/365 for student 3 and so on until you get all 10 students.
If you multiply all these values together, the probability would come out at around 0.88305182223 or 0.88.
To get all the same birthday you'd have to the chance of one birthday, 1/365 and multiply this by itself 10 times. This will produce a very tiny number. In standard form this would be 2.3827x10'-26 or in normal terms: 0.23827109210000000000000000, so very small.

A.) The current reserve ratio is given by the fraction of the bank's total deposits held in reserves.
Given that the bank's total deposits is $7,200 and the reserves is $1,600, the current reserve ratio is given by:

b.) The loan portfolio is given by (total deposit - reserves) / total deposits
Thus, the loan portfolio of the given bank is given by:
The total number of Games.....TNG=24
Sports Related Games...............SRG=06
Role Playing Games.....................RPG=18 (24-6)
The ratio of Role Playing Games to Total Number of Games=RPG:TNG
18:24
3:4 is the answer. A ratio is actually a concept related to Division. Here in 18:24 you can divide both sides by 6 to reach the answer 3:4.
