Why if you flip a coin 1000 times you should get about 500 heads and 500 tails?

Because the probability of heads is 0.5 and the probability of tails is 0.5. That does not mean, however, that you will get exactly 500 of each outcome in 1000 trials. The more trials you perform, the closer to the theoretical probability you will get. You will be close with 1000 trials, but you will not be exact, unless you are very lucky.

What are the chances of 3 people in an office of 6 having the same birthday?

The probability that there will be 3 people born on one birthday, and 3 people born on a different birthday is 1x(1/365)2 x (364/365)3 as it doesn't matter which birthday is the one being shared. This number then needs to be multiplied by the number of possible ways the people can be arranged. For example it could be persons a, b and c sharing a birthday, or it could be persons c, e and f. The number of ways they can be arranged is 20, so multiply by 20 and we get 0.00014889. Thus there is a 0.014889% chance that an office of 6 people will have 3 who share a birthday.

Can the variance of a sample be larger than the sample mean?

Yes,

Mean is given by, E(X) sum of samples / no. of samples.

Variance is Var.(X) = E(X^2) - [E(X)]^2.

It is the 1st term which makes the variation of variance independent of mean.

In other words, Variance gives a measure of how far the samples are spread out.
