In an experiment we toss two unbiased coins 100 times and note the frequency of the two possible outcomes (heads, tails). We are interested in calculating the probability (or chance) that at least 1 head will occur from the 100 tosses of the 2 coins. Calculate:

(a) The theoretical probability that at least one head occurs, 

(b) The value of this probability from your experiment. What would you expect to occur between the theoretical and experimental probability values if the overall number of attempts increases?
