WebSolution: We can think of each question as a coin ip with P(H) = 1=5. If Xis the rst question answered correctly then Xis a geometric random variable with pmf P(X= k) = (1 p)k 1p= 4 5 k 1 1 5 = 4k 1 5k : Thus the probability that the rst correct answer occurs on question 4 is P(X= 4) = 43 54 = 10:24%: 2.3-14. WebSep 26, 2024 · I'm guessing you mean PMF since this is discrete.
