1) Choose the signature for methods that solve the following problems, or state that it is impossible to do so. You do not need to write these methods.

a- Generates a random integer between two given integers (inclusive).

b- Generates a random double between two given integers (exclusive).

c- Generates a random integer between two given integers (inclusive) that will be even or odd, depending on whether a given boolean is true (even) or false (odd).

d- Generates two random integers between two given integers.

e- Determines whether a given integer is or is not prime. Prime means that the number has no factors other than 1 and itself. Seven is prime. Eight is not prime because 2 and 4 are factors.
