2 coins are tossed at the same time There are 3 colums in a chart 1) Heads-Heads 2) Heads-Tails or Tails-Heads 3)Tails-Tails the coins were tossed 40 times simultaneously. What was the probability that heads-tails (or tails-heads) would appear? Show calculations. (HINT: The probability of these two combinations must be added together because they were recorded together.) Im thinking its 2/4 but not sure, and dont know what to show as calculations. PLEASE HELP ME!
