Coin Toss Probability:
From: | To: |
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.
The calculator uses the probability formula:
Where:
Explanation: Each coin toss is an independent event with two equally likely outcomes.
Details: Understanding basic probability is fundamental in statistics, gambling theory, decision making, and many scientific fields.
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.
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%
