A fair coin is tossed two times in succession. Let's return to the coin-tossing experiment. Runs of coins. However, if the first ball was red, there will be 1 red and 2 blue balls left so the probability the second ball is blue is 2/3. a die tossed n then a special coin is tossed. Players gamble on whether the coins will fall with both (obverse) heads up, both (reverse) tails up, or with one coin a head, and one a tail (known as 'Odds'). When we toss two coins simultaneously then the possible of outcomes are: (two heads) or (one head and one tail) or (two tails) i. The task is to find the probability of getting heads more number of times than tails. For the second part of question, you are not bothered with the results of 2nd to 6th toss. One of these three possible outcomes will be the experiment’s result. There is only one outcome that can be all tails, so the chances are 1 in 1024.
