Detailed explanation-1: -N=3: To get 3 heads, means that one gets only one tail. This tail can be either the 1st coin, the 2nd coin, the 3rd, or the 4th coin. Thus there are only 4 outcomes which have three heads. The probability is 4/16 = 1/4.
Detailed explanation-2: -Answer: The probability of flipping a coin three times and getting 3 tails is 1/8.
Detailed explanation-3: -Solution: Probability can be defined as the ratio of the number of favorable outcomes to the total number of outcomes of an event. Therefore, the probability of getting tails 4 times in a row is 1/16.
Detailed explanation-4: -Answer: If you flip a coin 3 times the probability of getting 3 heads is 0.125. When you flip a coin 3 times, then all the possibe 8 outcomes are HHH, THH, HTH, HHT, TTH, THT, HTT, TTT.
