## When an unbiased coin is tossed n times the probability to get head in each trial is?

If a coin be tossed n times then probability that the head comes odd times is. If a coin is tossed “n” number of times, the total sample space = 2n. Hence, the required probability = 2n-1/2n = ½.

**What is the probability of getting k heads in n tosses?**

So the probability will be 4/8 or 0.5.

### When we throw an unbiased coin then what is the probability of getting ahead?

When we flip a coin there is always a probability to get a head or a tail is 50 percent. Suppose a coin tossed then we get two possible outcomes either a ‘head’ (H) or a ‘tail’ (T), and it is impossible to predict whether the result of a toss will be a ‘head’ or ‘tail’. (i) If the favourable outcome is head (H).

**What is the probability of getting 2 head if you toss the coin twice?**

The probability of getting two heads on two coin tosses is 0.5 x 0.5 or 0.25.

#### What is the probability of getting exactly 2 heads when 3 coins are tossed?

3/8

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 a head when flipping an unbiased coin is shown by the letter?**

There are four equally likely possibilies, HH, HT, TH or TT, of which there are two, HH or HT, that have heads first. So the probability is 2/4 = 1/2. Notice this is the same as you would get if you tossed the coin once.

## What is the probability of two fair coins being tossed simultaneously?

Question: Two fair coins are tossed simultaneously. What is the probability of getting only one head? Solution: When 2 coins are tossed, the possible outcomes can be {HH, TT, HT, TH}. Thus, the total number of possible outcomes = 4. Getting only one head includes {HT, TH} outcomes. So number of desired outcomes = 2.

**How many possible outcomes are there when 3 coins are tossed?**

When 3 coins are tossed, the possible outcomes can be {HHH, HHT, HTH, HTT, THH, THT, TTH, TTT}. Thus, total number of possible outcomes = 8 Getting at least 2 tails includes {HTT, THT, TTH, TTT} outcomes.

### What is the probability of getting exactly six heads?

A coin is tossed 10 times. The probability of getting exactly six heads is A coin is tossed 10 times. The probability of getting exactly six heads is = 105/512.

**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.
