Ex 15.1, 25 Which of the following arguments are correct and which are not correct? Give reasons for your answer. (i) If two coins are tossed simultaneously, there are three possible outcomes, two heads, two tails or one of each. For each of these outcomes, the probability is 1/3 Total possible outcomes = (H, H) , (H, T), (T, H), (T, T) Number of possible outcomes = 4 Probability of getting two heads = (ππ’ππππ ππ π‘ππππ π‘π€π βππππ ππππ’ππ )/(πππ‘ππ ππ’ππππ ππ ππ’π‘πππππ ) Probability of getting two tails = (ππ’ππππ ππ π‘ππππ π‘π€π π‘ππππ ππππ’ππ )/(πππ‘ππ ππ’ππππ ππ ππ’π‘πππππ ) Probability of getting one head & one tails = (ππ’ππππ ππ π‘ππππ πππ βπππ πππ πππ π‘πππ ππππ’ππ )/(πππ‘ππ ππ’ππππ ππ ππ’π‘πππππ ) = 2/4 = 1/2 Therefore the given statement is incorrect. The probabilities of these outcomes is not 1/3
