A six-sided die is rolled, and the number N on the uppermost face is recorded. From a jar containing 10 tags numbered 1,2,...,10 we then select N tags at random without replacement. Let X be the smallest number on the drawn tags. Determine Pr{X=2}and E[X].

Please solve it step by step especially the expectation part. appreciate it.

You can draw some intuition graph and picture to help you explain
