Probability - Equally Likely Events | Tossing a Coin | Don't Memorise

## TL;DR

This video explores the probability of a coin landing on either heads or tails and how it relates to the likelihood of different outcomes in a coin toss.

## Key Insights

• #️⃣ Coin toss probabilities are calculated by dividing the number of ways a specific outcome can occur by the total number of possibilities.
• 🤕 The probability of landing on heads or tails in a coin toss is 1/2 or 0.5 because there is only one way to achieve each outcome and two total possibilities.
• ❓ Equally likely events have the same probability, indicating that their likelihood of occurrence is the same.
• 😑 Probability does not provide a definite answer but rather expresses the likelihood of an event occurring.

## Transcript

we will look at just one interesting Concept in this video and that is a coin toss you will not believe how interesting it is think about it when you toss a coin it will either land a head or a tail either head or tail all of us would agree that these are the only two possibilities suppose I ask you a simple question what is the probability of the ...

### Q: How do you calculate the probability of a coin landing on heads?

The probability of a coin landing on heads is calculated by dividing the number of ways it can land on heads (1) by the total number of possibilities (2), resulting in a probability of 1/2 or 0.5.

### Q: What is the probability of a coin landing on tails?

Similar to the probability of landing on heads, the probability of a coin landing on tails is also 1/2 or 0.5. This is because there is only one way to get tails and two total possibilities (heads and tails).

### Q: What does it mean when two events have the same probability?

When two events have the same probability, it signifies that they are equally likely to occur. In the case of a coin toss, getting heads or tails are equally likely events as both have a probability of 1/2 or 0.5.

### Q: Can we predict the exact outcome after 10 coin tosses?

No, the exact outcome of 10 coin tosses cannot be predicted with certainty. While the probability suggests that we should get approximately the same number of heads and tails, the actual outcome can vary, possibly resulting in six heads and four tails, nine heads and one tail, or some other distribution.

## Summary & Key Takeaways

• The video discusses the concept of coin toss probabilities and how to calculate the likelihood of a coin landing on heads or tails.

• It highlights that in a coin toss, there are only two possibilities: heads or tails.

• The probability of a coin landing on heads or tails is found by dividing the number of ways it can land on a particular outcome by the total number of possibilities.
