The sample space, S, for flipping a fair coin three time is shown below.

(H = heads up, T = tails up)
S = {HHH, THH, HTH, HHT, TTH, THT, HTT, TTT}

Brooklynn randomly draws cards from a deck of cards. She wants to draw any card that is a spade. Brooklynn uses a random number generator to simulate the situation. She assigns a number to each suit where 0 represents spades, 1 represents hearts, 2 represents diamonds, and 3 represents clubs. Her simulation had 25 trials and are listed below.

0 1 2 3 0 0 2 2 1 2 3 3 0 2 2 0 3 1 2 0 0 2 3 1 1

Using the results of her simulation, what is the experimental probability that she draws a spade?
