If a number cube is rolled 4 times, find the probability that an even number is rolled all 4 times. Thank you so much if you help me i am not very good at math... Answer by stanbon(75887) (Show Source):
You can put this solution on YOUR website! There are 3 even numbers on the cube, which has 6 faces.
What happens on the 1st roll has no effect on what happens
on the subsequent rolls. The rolls are independent.
Therefore you get (3/6)^4 as your answer.
The probability of getting an even number is 3/6 each time
you roll the dice.
