P. 306
Let us understand it using the example of a coin.
When a coin is tossed, there are two possible outcomes: head or tail.
What is the probability of getting a head?
1
P(Head) =
2
1 1
So, we see the chances of getting head is and the chances of getting tail is .
2 2
Therefore, we conclude that when we toss a coin, there are equal chances of getting a head or a tail.
Let us take another example, consider the probability of rolling a fair six-sided die.
A fair six-sided die has six faces numbered from 1 to 6.
The probability of rolling any specific number (say, 3) on a fair six-sided die is calculated as,
Number of favourable outcomes (rolling a 3) = 1
Total number of possible outcomes = 6 (since there are 6 faces on the die)
So, the probability of rolling a 3 on a fair six-sided die is:
Number of Favourable Outcomes 1
P(6) = =
Total Number of Possible Outcomes 6
Can you find the probability of getting an even number in a Dice?
Task #Experiential Learning
