What is the probability that x2 + 7x + k is factorable if 0 ≤ k ≤ 20 and k is an integer? Homework Help ✎
How many possible values are there for k? This is the denominator of the probability.
What numbers between 0 and 20 starting with 1 and going to 20 have two factors that add to 7? Note: 0 works because x would be a factor.
