General: Thumbtack Drop a thumbtack and observe how it lands.

(a) Describe how you could use a relative frequency to estimate the probability that a thumbtack will land with its flat side down.

(b) What is the sample space of outcomes for the thumbtack?

(c) How would you make a probability assignment to this sample space if when you drop 500 tacks, 340 land flat side down?
