1. Amy tosses 12 biased coins. Each coin comes up heads with probability 0.2. What is the probability that fewer than 3 of the coins come up heads?

Answer: 0.5583

2. Amy shoots 27000 arrows at a target. Each arrow hits the target (independently) with probability 0.2. What is the probability that at most 2 of the first 15 arrows hit the target?

Answer: 0.398

3. Amy tosses 19 biased coins. Each coin comes up heads with probability 0.1. What is the probability that more than 1 of the coins come up heads?

Answer: 0.5797

4. Amy shoots 49000 arrows at a target. Each arrow hits the target (independently) with probability 0.2. What is the probability that fewer than 3 of the first 12 arrows hit the target?

Answer: 0.5583

Coin 1 comes up heads with probability 0.6 and coin 2 with probability 0.5. A coin is continually ﬂipped until it comes up tails, at which time that coin is put aside and we start ﬂipping the other one. (a) What proportion of ﬂips use coin 1? (b) If we start the process with coin 1 what is the probability that coin 2 is used on the ﬁfth ﬂip? (c) What proportion of ﬂips land heads?

Find the probability of getting 8 heads in 12 tosses of a coin.

30.Consider a coin that comes up heads with probability p and tails with probability 1 − p. Let qn be the probability that after n independent tosses, there have been an even number of heads. Derive a recursion that relates qn to qn−1, and solve this recursion to establish the formula qn = 1 + (1 − 2p) n 2 Using method other than Mathematical Induction

A box contains three fair coins and one biased coin. For the biased coin, the probability that any flip will result in a head is 1/3. Al draws two coins from the box, flips each of them once, observes an outcome of one head and one tail and returns the coins to the box. Bo then draws one coin from the box and flips it. The result is a tail. Determine the probability that neither Al nor Bo removed the...

A magic shop sells a coin which is rather biased. It comes up heads 40% of the time. Suppose the shop owner puts on a demonstration his customers by flipping the coin 12 times. For each item below, write the letter which corresponds to the correct value. Some letters may not be used and some letters may be used more than once. • Probability of exactly 6 heads? • Probability of exactly 9 tails? • Probability of more than than...

Please give detailed solution for this Coin 1 comes up heads with probability .3, whereas coin 2 comes up heads with probability .6. A coin is randomly chosen and flipped 10 times. (a) Find the probability the first flip lands heads. (b) Find the expected number of heads in the 10 flips. (c) Find the probability that there are a total of 7 heads.

Suppose we have a biased coin that comes up heads 55% of the time. We perform an experiment where we toss the coin until the first tails appears. Let T be the number of tosses until the first tails. What is the expected value and standard deviation for T? What is the probability that it takes 5 or more tosses before the first tails appears?

Flip a coin 10 times. Put a 1 each time the coin comes up heads and a 0 each time the coin comes up tails. Count the number of heads you obtained and divide by 10. What number did you get? a. Is the number you obtained in part (a) a parameter or a statistic? b. Now flip the coin 25 times. Put a 1 each time you obtain a heads and a 0 for tails. Count the number of...
