STATISTICS: What is the probability of getting 3 heads on 12 tosses of an un fair coin p(H)= 0.7?
The probability of getting heads from throwing a fair coin is 1/2 The fair coin is tossed 4 times. What is the probability that exactly 3 heads occur? 1/4 The fair coin is tossed 4 times. What is the probability that exactly 3 heads occur given that the first outcome was a head? 3/8 The fair coin is tossed 4 times. What is the probability that exactly 3 heads occur given that the first outcome was a tail? 1/8 The...
Brayden tosses a coin 500 times. of those 500 times, he observes heads a total of 416 times. Calculations show that the probability of this occurring by chance is less than 0.01, assuming the coin is fair. Determine the meaning of the significance level Select the correct answer below: O We expect that 416 of every 500 coin tosses will result in heads. O At the 0.01 level of significance, the coin is likely not a fair coin O There...
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 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.
A statistics student reported getting 9207 heads and 8743 tails out of 17950 coin tosses. is this evidence that the coin is fair? coclysion at the 1percent level
Given 5 consecutive tosses of a fair coin, what is the probability of getting three tails in a row, followed by two consecutive heads? 4.
a. Suppose that a fair coin is tossed 15 times. If 10 heads are observed, determine an expression / equation for the probability that 7 heads occurred in the first 9 tosses. b. Now, generalize your result from part a. Now suppose that a fair coin is to be tossed n times. If x heads are observed in the n tosses, derive an expression for the probability that there were y heads observed in the first m tosses. Note the...
