In a situation where we have a biased coin that is tails with probability 0.7 and we independently flip it 10 times. Find the following probabilities.

1. getting the sequence HTHHHTHTTH?

2. exactly 4 tails?

3. at least 4 tails?

4. expected number of tails? expected number of heads?

Deriving fair coin flips from biased coins: From coins with uneven heads/tails probabilities construct an experiment for which there are two disjoint events, with equal probabilities, that we call "heads" and "tails". a. given c1 and c2, where c1 lands heads up with probability 2/3 and c2 lands heads up with probability 1/4, construct a "fair coin flip" experiment. b. given one coin with unknown probability p of landing heads up, where 0 < p < 1, construct a "fair...

A selection of coin is known to be either fair (with a probability 0.5 of coming up heads or tails when flipped) or biased (with a probability 0.75 of tails, 0.25 of heads.) Further. it is known that 1/10 of the coins are biased. a) You select a coin at random. What are the prior odds (not probability) that you have picked a biased coin? b) You select a coin at random and flip it; you get tails. What are...

Conducting a Simulation For example, say we want to simulate the probability of getting “heads” exactly 4 times in 10 flips of a fair coin. One way to generate a flip of the coin is to create a vector in R with all of the possible outcomes and then randomly select one of those outcomes. The sample function takes a vector of elements (in this case heads or tails) and chooses a random sample of size elements. coin <- c("heads","tails")...
