WebbWhen a coin is tossed, there are only two possible outcomes. Therefore, using the probability formula. On tossing a coin, the probability of getting a head is: P (Head) = P (H) = 1/2. Similarly, on tossing a coin, the probability of getting a tail is: P (Tail) = P (T) = 1/2. Try tossing a coin below by clicking on the 'Flip coin' button and ... WebbThere are two useful rules for calculating the probability of events more complicated than a single coin toss. The first is the Product Rule. This states that the probability of the occurrence of two independent events is the product of their individual probabilities. The probability of getting two heads on two coin tosses is 0.5 x 0.5 or 0.25.

Calculation: When three coins are tossed then the outcome will be any one of these combinations. (TTT, THT, TTH, THH. HTT, HHT, HTH, HHH). So, the total number of outcomes is 8. Now, for exactly two heads, the favorable outcome is (THH, HHT, HTH).

Webb15 mars 2024 · We're asked for the probability of getting EXACTLY three heads on five flips of a fair coin. This question can be approached in a couple of different ways, but they all involve a bit of 'Probability math.' To start, since each coin has two possible outcomes, there are (2)(2)(2)(2)(2) = 32 possible outcomes from flipping 5 coins. WebbSolution (i): Let E be the event of getting exactly two heads Therefore, no. of favorable events, n(E)=3(i.e.,HHT,HTH,THH) We know that, P(E) = (Total no.of possible outcomes)(No.of favorable outcomes) = 83 Solution (ii): Let F be the event of getting atmost two heads Therefore, no. of favorable events, n(E)= …
