<u>The </u><u>probability</u><u> of getting an even number at least once will be </u><u>1/4.</u>
What is probability called?
The ratio of the number of outcomes in an exhaustive set of equally likely outcomes that produce a given event to the total number of possible outcomes.
It is given that a fair dice is rolled twice. The probability of getting an even number at least once will be calculated as:-
Number of favorable outcomes = { 2 , 4 , 6 } = 3
It is rolled two times total favorable outcomes = 3 x 3 = 9
Number of samples = 6 x 6 = 36
The probability will be calculated as:-
Probability = Number of favorable outcomes / Number of sample
Probability = 9 / 36
Probability = 1 / 4
Therefore, the probability of getting an even number at least once will be 1/4.
