PLZ HELPIvan 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?

Answer:300Step-by-step explanation:A number cube has total six possible outcomes:1, 2, 3, 4, 5 and 6Probability of the occurrence of each side is: 1/6 From the possible outcomes, the even number are 2,4,6Therefore the probability of the occurrence of an even number is:1/6 + 1/6 + 1/6=> 3/6=> 1/21/2 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
