1. Find the total possible amount of eight-digil palindromics. Also, how many nine-digit palindromics are there? (Palindromic: a number whose digits read the same backwards and forwards.) 2. Suppuse Alice has 5 red balis and 4 green builis. She wants to arrange all the balls in a row in such a way that the red balls occupy the odd positions. How many arrangements are possible? 3. Suppose there is a set of 10 vegetables. In how many ways, 6 vegetables can be selected from this set (without repetition)? 4, Suppose there is a set of 8 candies. In how many ways, 4 candies can be selected from this set (without repetition)?
