Answer 1

Answer:

B) 300

Step-by-step explanation:

A six sided cube has 6 sides numbered 1, 2, 3, 4, 5 and 6.

Each time you roll it, you have a 1/6 chance of any number.

So, in 600 rolls, we'd expect to get 100 of the number 1, 100 of the number 2, 100 of the number 3, etc...

So how many times would you expect a 2, 4, or 6?

That's half of the possible numbers. (1/6 + 1/6 + 1/6 = 3/6 = 1/2)

So 1/2 * 600 = 300 times.

Pick answer B.

Answer 2

Answer: B

Step-by-step explanation:

- The probability of rolling a 2, 4, or 6 on one roll is all the probabilities added up from each number individually:

P(rolling a 2) + P(rolling a 4) + P(rolling a 6) = 1/6 + 1/6 + 1/6 = 3/6 = 1/2.

- The probability of rolling a 2, 4, or 6 on a single roll is 1/2.

- Now, to find the he expected number of times a 2, 4, or 6 would show up in 600 rolls, we multiply the probability of it happening once by the total number of rolls:

(1/2) * 600 = 300 (1/2 the probability, and 600 being the amount of rolls done).
