The terms in the formula are as follows: P is the present value, or the amount that you need to deposit toda F is the future value that you want in the account. (In this case, r is the annual interest rate. n is the number of years that you plan to let the money sit in t Write a function named Presentvalue that performs this calculation. The func tion should accept the future value, annual in arguments. It should return the present value, which is the amount that you nee to de terest rate, and number of years posit today. Demonstrate the function in an app that lets the user ex ment with different values for the formula's terms. Rock, Paper, Scissors Game Create an app that lets the user play the game of Rock, Paper, Scissors againstt Android device or emulator. The app should work as follows. 1. When the app begins, a random number in the range of 1 through 3 is generated. If the number is 1, then the device has chosen rock. If th number is 2, then the device has chosen paper.
