My friend and I are playing a probability game. We would draw from a bag of marbles. There are 5 blue, 10 red, 3 black, and 2 yellow. Given that there are 20 marbles total. What is the probability of drawing a yellow marble?

1c) the number 131 is a term in the sequence defined by the explicit rule f(n)=5n-4. which term in the sequence is 131? 2a) write the first four terms of the function f(n)=n^2-1 2b) what is the 10th term of the sequence defined by the explicit rule f(n)=n^2-1 2c) the number 224 is a term in the sequence defined by the explicit rule f(n)=n^2-1. which term in the sequence is 224?
