# Probability with Venn Diagrams – Ultimate Guide

It is quite often to visualise multiple events using Venn diagrams to find probabilities. Representing Data in Venn Diagrams There are 9 types of Venn diagrams for holding two events when they overlap each other. Let’s assume there are two elective subjects, Arts and Biology, in a certain school. $P(A)$ The probability that […]

# Probability without Replacement and Order of Events

Transcript A box contains 40 red, 10 blue, and 10 white cards. Two are withdrawn, one after the other without a replacement. So there’s no replacement here. Find the probability that the first card is withdrawn. A first card is that is withdrawn is blue. Okay. So you can see that 40 plus 10 plus […]

# Probability without Replacement with AND OR

Transcript A box contains five light globes, two of which are faulty. Two globes are selected, one at a time without replacement. Now, a! Find the probability that both globes are faulty. Now, two are faulty out of the five, so two out of five are faulty globes. Now we want, we know that there’s […]

# Product Rule and Independent Events

Transcript Single digits are being generated randomly, so like these kind of numbers. It doesn’t have to be a five-digit number but these are the kind of things randomly generated. It can be any random number, okay? And it can be repeated or there’s no limit to this. So it’s like these kind of numbers. […]

# Product Rule of Probability: Probability Regarding AND

Transcript They give you probability of a, b, c, and d in the question. Part a! They want us to find probability of a and b. Probability of a and b is simply probability of a times the probability of b which becomes 1 on 24. And that’s it, guys. That’s pretty much the product […]

# Addition Rule and Mutually Exclusive Events

Transcript Okay, if a and b are mutually exclusive and they give you what probability of a and probability of b is. They want us to find the probability of a or b. Now, the key thing here is mutually exclusive. What does mutually exclusive mean? Mutually exclusive means the probability of a and b […]

# Probability Regarding OR

Transcript Two dice are thrown. One yellow and one white. Let y be the uppermost number on the yellow die and w be the uppermost number on the white die. I’ve drawn up a table because I know that if I drop a table, the questions will be so much easier. So I do recommend […]
