Sarah rolls two six-sided number cubes each with sides labeled from 1 to 6. let a be the event where one cube lands on 1 and the other cube lands on 6. what is the probability of the complement of a?
katrillion isn't a real value but everything else is.
25 and -31
notice that if all the negatives were positive, you would have the arithmetic sequence 1, 7, 13, 19, on and on, adding 6 every time. so basically we have a geometric and arithmetic sequence combined, with the geometric sequence making it positive, and negative, and the arithmetic sequence adding 6 every time. this means the answer(s) are 25 and -31.
hope this !
