How to write a python program for these two questions ?

2. The value of a can be computed according to the following formula: = 3+ ++ 2x3xa exxo * ox7x8_8x9x 10 **** Write a program to compute n. Because the formula is an infinite series and an algorithm must stop after a finite number of steps, you should stop when you have the result determined to six significant digits. Report the number of the iterations. 3. Let (a,b) denote a possible outcome of rolling a pair of dice, with a to be the number on the top of the first die and b the number on the top of the second die. Develop a program that enumerates all (a,b) values and calculates. It also tabulates (a+b) in a table, where the sum for (a,b) is in the cell for the row a and column b, as shown below: 2 3 4 5 6 3 4 5 6 4 5 6 7 5 189 6 7 8 N00193 10 6 7 8 9 7 8 9 10
