Detailed explanation-1: -‘ P(getting a head) <br> = P(H) = ‘("number of favourable outcomes")/("total number of possible outcomes “) = 1/2‘.
Detailed explanation-2: -The probability of heads on the first toss is 50%, just as it is on all subsequent tosses of the coin. The two outcomes of the toss of a coin are heads or tails. For any individual toss of the coin, the outcome will be either heads or tails.
Detailed explanation-3: -The probability is therefore 1/16. N=1: There are 4 possible outcomes which will have only one coin heads.
Detailed explanation-4: -If you flip a coin 4 times the probability of you getting at least one heads is 15 in 16 because you times the amount of outcomes you can get by flipping 3 coins by 2, it results in 16 and then you minus 1 from it.
