A special novelty coin has a probability of 0.89 of coming up heads. In 12 tosses of this coin: a) What is the probability the coin comes up heads exactly 10 times? Round your response to at least 3 decimal places. b) What is the probability the coin comes up heads more than 10 times? Round your response to at least 3 decimal places.
question1: Suppose A, B & C are independent events with common probability = .20 Determine P(A U B U C) question2: A coin with P(heads) = p is tossed until heads appears. Determine the probability it takes an odd number of tosses.
A biased coin is tossed n times. The probability of heads is p and the probability of tails is q and p=2q. Choose all correct statements. This is an example of a Bernoulli trial n-n-1-1-(k-1) p'q =np(p + q)n-1 = np f n- 150, then EX), the expected value of X, is 100 where X is the number of heads in n coin tosses. f the function X is defined to be the number of heads in n coin tosses,...
a fair coin is tossed until either a head turns up or 3 tosses are made. let x be no of heads which occur and let y be no of tails. find expected value and variance of x and y
Consider a coin whose probability of landing heads is p. For what values of p can you guarantee that the probability of obtaining: (i) at least one heads in 6 tosses is strictly less than .15? (ii) exactly 3 heads in 6 tosses is strictly less than .15?
You toss a coin 1000 times The probability that a coin comes up heads 12 times in 12 tosses is
A defective coin minting machine produces coins whose probability of heads is a random variable P with PDF peP, p [0,1], otherwise fp(p) A coin produced by this machine is selected and tossed repeatedly, with successive tosses assumed independent. (a) Find the probability that a coin toss results in heads. (b) Given that a coin toss resulted in heads, find the conditional PDF of P (c) Given that a first coin toss resulted in heads, find the conditional probability of...
Derive the sampling distribution for the number of heads in 3 tosses of a a) fair coin b) biased coin with p (head) = .7
A coin with probability p of heads is tossed until the first head occurs. It is then tossed again until the first tail occurs. Let X be the total number of tosses required. (i) Find the distribution function of X. (ii) Find the mean and variance of X
STATISTICS: What is the probability of getting 3 heads on 12 tosses of an un fair coin p(H)= 0.7?
