Histogram of X 0.4 Relative Frequency 0.
Consider the experiment of dropping 5 thumb tacks and noting how each tack lands: either point up or point down.
1.Let X = number of tacks that land point down out of the 5.
Assuming that the tacks are fair, complete the probability distribution below.

2. Suppose you obtain 50,000 of these tacks all made at the same location by the same manufacturer. You take 5 tacks at a time, drop them, and record X = the number of tacks that land point down. You then obtain a histogram of the 10,000 values of X. The histogram is shown in the attached pdf file below.
What would you conclude?
