ivan is doing an experiment with a number cube. about how many times should he expect to roll an even number on the number cube if he rolls it 600 times?

300

Step-by-step explanation:

A number cube has total six possible outcomes:

1, 2, 3, 4, 5 and 6

Probability of the occurrence of each side is: 1/6

From the possible outcomes, the even number are 2,4,6

Therefore the probability of the occurrence of an even number is:

1/6 + 1/6 + 1/6

=> 3/6

=> 1/2

1/2 probability shows that if a number cube is rolled 'n' times, (1/2)*n number of chances are it is an even number.

So the expectation of rolling an even number with 600 trials is:

(1/2)*600

=> 300    

its numbers

Step-by-step explanation:

answer: 1) twenty-seven times y

              2) twenty-seven multiplied by y
