Luis has a coin that is weighted so that the probability that Heads appears when it is tossed is 0.55. Suppose that the coin is tossed 3 times. What is the probability that all 3 tosses are Heads?please help ,e to solve this question .i dont'know if i +am right.55/2+.55/2+.55/2= 1.65/2 =0.82 AnswerAm i right ?
One coin is weighted so that the probability that it lands tails up is 25%. Another coin is weighted so that the probability that it lands tails up is 85%. If each coin is tossed 5 times and the total number of tails is recorded, the results will not form a binomial distribution for which reason(s)? (select all that apply) Each trial has more than 2 possible outcomes. The trials are dependent There is not a fixed number of trials....
A coin is weighted so that there is a 62% chance that it will come up "heads" when flipped. The coin is flipped four times. Find the probability of getting two "heads" and two "tails". Round your answer to four decimal places.
A coin is weighted so that there is a 65% chance that it will come up "heads" when flipped. The coin is flipped four times. Find the probability of at least one of the flips resulting in "tails". Round your answer to four decimal places.
A coin is weighted so that the probability of obtaining a head in a single toss is 0.6. If the coin is tossed 25 times, find the following probabilities. (Round your answers to fou decimal places.) (a) fewer than 12 heads 0.0778 (b) between 12 and 15 heads, inclusive 4970 X (c) more than 19 heads You may need to use the appropriate table in the Appendix of Tables to answer this question Need Help? med 16.

A coin is weighted so that it is twice as likely to fall heads as it is tails. If you toss the coin four times, what is the probability of getting four heads is a row?
A coin is tossed 5 times. What is the probability that the number of tails obtained will be 1? Express your answer as a fraction or a decimal number rounded to four decimal places.
Use the appropriate normal distribution to approximate the resulting binomial distribution A coin is weighted so that the probability of obtaining a head in a single tos:s is 0.6. If the coin is tossed 30 times, find the following probabilities. (Round your answers to four decimal places.) (a) fewer than 15 heads (b) between 15 and 19 heads, inclusive (c) more than 22 heads
A coin is tossed 7 times. What is the probability that the number of tails obtained will be between 1 and 3 inclusive? Express your answer as a fraction or a decimal number rounded to four decimal places.
(a) [15 points] Suppose you have a weighted coin in which heads comes up with probability 3/4 and tails with probability 4. If you flip heads you win $2, but if you flip tails, you lose $1. What is the expected value of a coin flip?
