Combination Of Events
An event where two or more mutually exclusive events occur simultaneously is said to be a combination of event. For example while throwing a dice and picking a card from a deck of cards is happening simultaneously.
In such a situation the sample space if calculated by multiplying the total outcomes in each case.
For example For combination of event of throwing a dice and picking a card from a deck of cards
The sample space while throwing a dice = 6
The sample space of picking a card from a deck of cards = 52
So the sample space of the event of throwing a dice and picking a card from a deck of cards
= Sample space while throwing a dice X Sample space for picking a card from a deck of cards
= 6 X 52 = 312
From the sample space we will calculate the favorable outcomes and will then calculate the probability.
Illustration: A dice and a coin is thrown simultaneously. Find the probability of getting a head and 2 on the dice.
Solution: Now throwing a dice and tossing a coin are two mutually exclusive events. So the sample space is calculated by multiplying the total outcomes in each case

When I have not joined Abhyas Academy, my skills of solving maths problems were not clear. But, after joining it, my skills have been developed and my concepts of science and SST are very well. I also came to know about other subjects such as vedic maths and reasoning.
