<h3>
Answer: 4/13</h3>
=======================================================
Explanation:
There are A = 13 hearts and B = 4 copies of "7"
The count A+B = 13+4 = 17 may seem like it's the count of hearts or "7" cards, but we're double counting the 7 of hearts. So the true count is actually 17-1 = 16
There are 16 cards we want (either a heart or a "7") out of 52 total. Therefore, the probability is 16/52 = (4*4)/(4*13) = 4/13
Answer:
We are given 5 footballs and 9 baseballs. Therefore, the ratio would be 5:9, or 5/9 as the footballs would come first, then the baseballs.
G(x) − f(x) = x^2 - (<span> 3x + 5)
