Apologies as I have asked one of the 2 following questions previously on this Forum or another Forum, but I can't find what I am looking for.

1) What is my player advantage if I know that whenever there is a '6' card, an Ace will be the very next card 15.1% of the time? Isn't the answer something like (51% X .151) minus something?

2) What is my player advantage if I know that whenever there is a TEN, an Ace will be the very next card 15.1% of the time? I am wondering if this scenario is different from 1) above simply because there are 4 more times that I may be correct in predicting an Ace only due to chance because there are 4 times more 10s than there are 5s, or am i engaging in erroneous thinking?

Thank you in advance.
