Step 1
Let $P(T)$ be the probability of getting a tail, so $P(T) = 1 - p$. The coin is tossed twice. We want to find the probability that the same result is obtained on both throws. This means either both throws are heads (HH) or both throws are tails (TT). The Show more…

Consider two unfair coins, one that has probability p1 of coming up heads and the other that has probability p2 of coming up heads and assume that p2 ≠ p1. The first coin is tossed until a head appears and then the second coin is tossed until a head appears. If X equals the total number of these tosses, compute, in terms of p1, p2, q1 = 1−p1 and q2 = 1−p2, themostprobablevalueforXanddeterminethisresultwhenp1 =0.2andp2 =0.1.

1. A biased coin has probability p = 0.6 of coming up Heads. The coin is tossed 5 times. Assume that the tosses are independent. (a) What is the probability that the first two tosses are Heads, and the last three are Tails? (b) What is the probability that the first two tosses are tails? (c) What is the probability that at least two of the tosses come up Heads, in any order?
