Detailed explanation-2: -(b) When two coins are tossed together. There are four possible outcomes HH, HT, TH, TT.
Detailed explanation-3: -∴The total number of possible outcomes after 4 times = 2 × 2 × 2 × 2= 16.
Detailed explanation-4: -Outcome-Flipping Two Coins. In an experiment of flipping two coins, there are four possible outcomes.
Detailed explanation-5: -The probability of getting heads on the toss of a coin is 0.5. If we consider all possible outcomes of the toss of two coins as shown, there is only one outcome of the four in which both coins have come up heads, so the probability of getting heads on both coins is 0.25.
