## What is the probability of getting a head or a tail when a fair coin is tossed?

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’.

What is the probability of obtaining two heads and one tail when a fair coin is tossed three times?

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 a tail when a coin is tossed 3 times?

1/8
Answer: The probability of flipping a coin three times and getting 3 tails is 1/8.

How do you find the probability of heads and tails?

Therefore, using the probability formula:

1. On tossing a coin, the probability of getting head is: P(Head) = P(H) = 1/2.
2. Similarly, on tossing a coin, the probability of getting a tail is: P(Tail) = P(T) = 1/2.

#### What is the probability of getting at least 3 heads?

Since each of ht 4 flips has 2 possible outcomes (heads or tails), there are 24=16 outcomes in the sample space. At least 3 heads means 3 or 4 heads. (43)=4 ways to get 3 heads.

When 4 fair coins are tossed together what is the probability of getting at least 3 heads?

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.

## What is the probability of getting 2 heads in 3 tosses?

1/2
Answer: If you flip a coin 3 times, the probability of getting at least 2 heads is 1/2.

What is the probability of getting no head when two coins are tossed simultaneously?

Let E4 = event of getting no head. Then, E4 = {TT} and, therefore, n(E4) = 1. Therefore, P(getting no head) = P(E4) = n(E4)/n(S) = ¼.

### What is the probability of getting 3 heads in 3 tosses?

0.125
Answer: If you flip a coin 3 times the probability of getting 3 heads is 0.125.

Is heads or tails more likely?

Most people assume the toss of a coin is always a 50/50 probability, with a 50 percent chance it lands on heads, and a 50 percent chance it lands on tails. Not so, says Diaconis. If you flip a coin quite vigorously, it’s as close to being a fair event—50/50—as I know, if you flip it and catch it on your hand…
