What is the probability of getting two heads and one tail when three coins are tossed together?

3/8
What is the probability of two heads and one tail? Summary: The Probability of getting two heads and one tails in the toss of three coins simultaneously is 3/8 or 0.375.

What is the probability of getting two heads and a tail in any order?

The probability of getting HHT is 1 out of 8.

What is the probability of having 3 tails?

1/8
If three coins are flipped, the probability of getting exactly 3 tails is 1/8.

What is the probability of at least two heads on 3 coins?

If you toss 3 coins, at least two will be heads (P) or at least two will be tails (Q). There’s no other possible outcome. And, since the sum of all probabilities is 1, P + Q = 1. But because of the symmetry of the problem, the probability of at least two heads (P) is the same as the probability of at least two tails (Q).

What if my heads and Tails don’t have the same probability?

(Optional) If your heads and tails don’t have the same probability of happening, go into advanced mode, and set the right number in the new field. Remember that in classical probability, the likelihood cannot be smaller than 0 or larger than 1. The coin flip probability calculator will automatically calculate the chance for your event to happen.

What is the probability of getting all tails when 3 coins are tossed?

When 3 unbiased coins are tossed once. When 3 coins are tossed, the possible outcomes are HHH, TTT, HTT, THT, TTH, THH, HTH, HHT. The sample space is S = { HHH, TTT, HTT, THT, TTH, THH, HTH, HHT} (i) Let E 1 denotes the event of getting all tails. Hence the required probability is ⅛.

When 3 unbiased coins are tossed once what are the possible outcomes?

When 3 unbiased coins are tossed once. When 3 coins are tossed, the possible outcomes are HHH, TTT, HTT, THT, TTH, THH, HTH, HHT. (i) Let E 1 denotes the event of getting all tails. Hence the required probability is ⅛. (ii) Let E 2 denotes the event of getting two heads.
