Write the recursive formula for the followings sequence:
-4, -2, 1, 5, 10

Suppose i flip two identical coins. what is the probability that i get one head and one tail?

I’m still confused on how to work the percentages

For the chance to be team captain, the numbers 1-30 are put in a hat and you get two chances to pick a number, without replacement. which formula correctly shows how to find the probability that you choose the number 1 and then 2?
