Answer:
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
