Answer:
The 4 possible outcomes are HH, HT, TH, TT.
So theoretically, HH should occur 1in 4 times.
1/4 = x/20
x = 5
So why is it actually 2 in 20 when theoretically it should be 5 in 20? One reason is that theoretical probabilities gain more accuracy with larger numbers of results (e.g tossing the coins 100 times). You can likely think of some more reasons.
