You and a friend are talking about the probability of getting a heads on a single toss of a fair coin. Your friend insists that you are more likely to get a heads on a single toss of a fair coin than a tails. Is your friend correct, why or why not? If we were to toss the fair coin an infinite number of times, what would we expect?

On a single toss of a fair coin, the probability of heads is 0.5 and the probability of tails is 0.5. If you toss a coin twice and get heads on the first toss, are you guaranteed to get tails on the second toss? Explain.Explain why – 0.41 cannot be the probability of some event.Explain why 1.21 cannot be the probability of some event.Explain why 120% cannot be the probability of some event.Can the number 0.56 be the probability of...
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?
Suppose we toss a weighted coin, for which the probability of getting a head (H) is 60% i) If we toss this coin 3 times, then the probability of getting exactly two heads (to two decimal places) is Number ii) If we toss this coin 6 times, then the probability of getting exactly four heads (to two decimal places) is Number CI iii) if we toss this coin 8 times, then the probability of getting 6 or more heads (to...
You toss a fair coin four times in a row. What is the probability of getting four tails?
3) We roll 2 fair dice. a) Find the probabilities of getting each possible sum (i.e. find Pr(2), Pr(3), . Pr(12) ) b) Find the probability of getting a sum of 3 or 4 (i.e.find Pr(3 or 4)) c) Find the probability we roll doubles (both dice show the same value). d) Find the probability that we roll a sum of 8 or doubles (both dice show the same value). e) Is it more likely that we get a sum...
A fair coin is tossed 6 times. A) What is the probability of tossing a tail on the 6th toss given the preceding 5 tosses were heads? B) What is the probability of getting either 6 heads or 6 tails?
If you flip a fair coin six times, what is the probability of having more heads than tails?
We have four fair coins, each of which has probability 1/2 of having a heads outcome and a tails outcome. The experiment is to ip all four coins and observe the sequence of heads and tails. For example, outcome HTHH means coin 1 was heads, coin 2 was tails, coin 3 was heads, coin 4 was heads Note that there are 16 total outcomes, and we assume that each one is equally likely. What is the probability that at there...
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?(B) What is the probability of getting either 9 heads or 9 tails?
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...
