A six-sided number cube is rolled five times, X is the number of times an even number is rolled.
Which statement is true about this situation?
The variable X has a binomial distribution. P(success)=0.5; number of trials = 5 true
A binomial distribution for a random variable X is one in which there are only two possible outcomes, success and failure, for a finite number of trials.
We define success as “rolling an even” and failure as “not rolling an even.” In this case, each roll of the die would be a trial.
P(success of getting an even)=3/6*=1/2
The variable X has a binomial distribution. P(success)=0.5; number of trials = 5
