If you roll two fair six-sided dice, what is the probability that both dice show an odd number?
Solution:
Probability can be defined as the ratio of the number of favorable outcomes to the total number of outcomes of an event.
For an experiment having n number of outcomes, the number of favorable outcomes can be denoted by :
Let ‘x’ be the number on the first dice
‘Y’ be the number on second dice
First dice showing odd number = {1,3,5}
Second dice also has odd number = {1,3,5}
The probability that the first dice shows an odd number = 3/6.
The probability that the second dice shows an odd number = 3/6.
The possible results are (1,1), (1,3), (1,5), (3,1), (3,3), (3,5), (5,1), (5,3), (5,5).
The probability that both dice show an odd number is (3/6) × (3/6)
= 9/36
= 1/4
Therefore, the probability of getting an odd number in both dice is 1/4.
If you roll two fair six-sided dice, what is the probability that both dice show an odd number?
Summary:
If you roll two fair six-sided dice, the probability that both dice show an odd number is 1/4.
