1. What is Coin Toss Probability?

The probability of getting heads or tails in a fair coin toss is always 1/2 or 50% for a single toss. For multiple independent tosses, the probability is calculated by multiplying the individual probabilities.

2. How Does the Calculator Work?

The calculator uses the probability formula:

\[ P = \frac{1}{2}^n \]

Where:

Explanation: Each coin toss is an independent event with two equally likely outcomes.

3. Importance of Probability Calculation

Details: Understanding basic probability is fundamental in statistics, gambling theory, decision making, and many scientific fields.

4. Using the Calculator

Tips: Enter the number of tosses and select your desired outcome (heads or tails). The calculator will show the probability of getting that outcome in all tosses.

5. Frequently Asked Questions (FAQ)

Q1: Is a coin toss really 50/50?
A: For a fair coin, yes. In reality, there might be slight biases due to imperfections in the coin or tossing method.

Q2: What's the probability of getting at least one head in two tosses?
A: 75% (1 - probability of two tails = 1 - 0.25 = 0.75)

Q3: Does previous toss affect the next one?
A: No, each toss is independent (assuming a fair coin) - this is known as the Gambler's Fallacy.

Q4: How does this relate to binomial distribution?
A: Multiple coin tosses follow a binomial distribution where n=number of trials and p=0.5.

Q5: What if I want exactly 3 heads in 5 tosses?
A: The probability would be C(5,3) × (0.5)^5 = 10 × 0.03125 = 0.3125 or 31.25%
