Question

John is about to roll a six-sided, fair number cube 60 times. He wants to predict how many times the cube will land on an even number. He makes a prediction of 20 times. Is it a good prediction? What would your prediction be based on theoretical probability

Answer 1

Even numbersso each dice has numbers1,2,3,4,5,6the eve numbers are2,4,6odd are others1,3,5so 1/2 are odd
therefor 1/2 of 60 is how many times it would get even1/2 of 60=1/2 times 60=30
No not good predicitionmy prediction would be 30 times

Answer 2

Answer:

A number cube has 3 even numbers. Each even number has a theoretical probability of 1/6. In 60 rolls, an even number could come up ten times. Since there are 3 even numbers, the total predicted value is 30. So 20 is a low prediction.
