Answer with explanation:
An experiment is said to be binomial, if it has n number of trials,and out of n trials,when each trial is performed Independently, there are only two possible outcomes,one Success and other will be failure.
In option A,
Number of trials = 24,which is fixed.
Success= getting 4,when a die is rolled.
Failure = Getting ,number other than,4 , that is , 1,2,3,5,6.
So, This is Binomial Experiment.
In Option B,
Number of trials is not fixed.So, This is not Binomial Experiment.
In Option C
Number of trials is not fixed.So, This is not Binomial Experiment.
In Option D
Number of trials = 24
But, there are more than two possible outcomes.So,this is not a Binomial Experiment.
Correct Option : A
