Abox contains 4 oranges, 9 apples, and three pears. liliana selects a piece of fruit from the box at random. what is the probability that she selects an orange or a pear?

Me! i really need to get this right before 9. prove the divisibility of 7^6+7^5-7^4 by 11. use factoring so you get a number times 11. just tell me the number. i need this done asap
