If the relative frequency of getting a 'six' on a dice is 0.2, how many sixes would you expect to get in 200 throws of the dice?

If the relative frequency of a six is  0.2 , then here are
two conclusions that can be drawn:

1). In 200 throws, you can expect to see a 'six' (200 x 0.2) = 40 times.

2). That cube is not honest, and you should not participate in a game
where it's used.  The relative frequency of any number ... 1, 2, 3, 4, 5,
or 6 ... should be 0.1666... .  That particular cube is coming up '6' about
20% more often than it should.
