I am struggling to answer both of these questions can anyone help

9. Diphthong: Do problem 22 from Lippman p. 311 (pdf page 33). We are sampling these slips of paper without replacement, meaning that after a slip is drawn, it is not replaced back into the hat. Suppose you write each letter of the alphabet on a different slip of paper and put the slips into a hat. If you pull out two slips at random, find the probability that both are vowels.

10. Fourth Roll: Do problem 40 from Lippman p. 313 (pdf page 35). Find the probability of rolling a "1" on a fair die, given that the last 3 rolls were all ones.
