Probability of n heads in 2n tosses

WebbAlice tosses two biased coins, each of which has a probability of obtaining a head, simultaneously and repeatedly until she gets two heads. This happens on the rth toss for some integer r≥1. There is 36% chance that r is even, what is the value of p? Two biased coins. Coin A , p (A) to get H Coin B , p (B) to get H It is not clear whar is p? WebbFor example, if the outcome is hht, then N (hht) = 2. Suppose that the random variable X is defined in terms of N as follows: X=2N-2N²-3. The values of X are given in the table below.

WebbThe total number of possible sequences from n coin tosses is 2 n. So the probability that no two consecutive heads occur in n coin tosses is f (n) / 2 n. By enumeration, f (1) = 2, since we have {H, T}, and f (2) = 3, from {HT, TH, TT}. We then derive a recurrence relation for f (n), as follows. WebbLet's start, you have 2 discrete random variables, X and Y, where X is the amount of heads in the first n tosses, and where Y is the amount of heads in the last n tosses. Let's note that they're i.i.d. (independent identically distributed) variables. Now, what you're asking is "what's P(X>=Y)?" hutch auction https://mihperformance.com
