Question

A coin is tossed 20 times. It lands on heads 9 times. Compare the experimental and theoretical probabilities. If they are not close, give a possible reason for the discrepancy.

Answer 1

20×9=180 it says times .A coin is tossed 20 times

Answer 2

There is a 50/50 (half) chance that the coin will land on heads and a 50/50 (half) chance it will land on tails. Therefore it could've landed on heads 10 times and tails 10 times (half). The coin landed on heads 9/20 times and the coin landed on tails 11/20 times. That means tails got 55% of the flips (dunno what to call it) and heads got 45%.
I hope this helps!
