What is the probability of tossing an unfair coin 19 times and having heads come up 12 or more times (P(T)=0.7)?
An unfair coin has probability 0.4 of landing heads. The coin is tossed seven times. What is the probability that it lands heads at least once? Round your answer to four decimal places. P (Lands heads at least once) -
what is the probability of tossing a coin 3 times and getting heads each time?
Tossing an unfair coin with P(H) = 0.6 and P(T) = 0.4. The coin is tossed 10 times (each toss is independent from others) and in any turn it shows heads, it is tossed again. We want to count the cases where the coin is tossed twice and the second toss, too, is head. For example, H T T T T T T T H T H T In this case, the count will be 1. Only the first turn...
a coin is weighted deliberately so that the probability of tossing heads is twice the probability of tossing tails. what is the probability of tossing three heads in a row? what is the probability of tossing three tails in a row? what is the relative probability of tossing three heads versus three tails?
A fair coin is tossed 9 times. (A) What is the probability of tossing a tail on the 9th toss, given that the preceding 8 tosses were heads? (B) What is the probability of getting either 9 heads or 9 tails? (A) What is the probability of tossing a tail on the 9th toss, given that the preceding 8 tosses were heads? (Type an integer or a fraction. Simplify your answer.) (B) What is the probability of getting either 9...
One application of an absolute value inequality is the concept of the unfair coin. If a coin is tossed 100 times, we would expect approximately 50 of the tosses to be heads; however this is rarely the case. Toss a coin 100 times to test this hypothesis. Record the number of times the coin is heads and the number of times the coin is tails on the lines below. You may want to ask someone to tally the results of...
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.
Need help and explanations Part II: 1. Your unfair coin comes up heads with probability 0.6. You lip it until you get four heads in a row. Let t be the expected mmber of times you fip. Write an equation for t. (Your equation, if solved., should give the value of t). 2. X ~ U[2,3]. Y = 4tX2. Find the correlation between X and Y, why isn't it 1? 3, X has cdf FX(t) = 1-e-t4 for 0 f...
5. A coin is bent so that the probability that it lands heads up is 213. The coin is tossed ten times. Find the probability that it lands heads up at most five times. Find the probability that it lands heads up more times than it lands tails up.
