array to work out the total heads and tails total_no_heads = sum(trials 1) total_no_tails = sum(trials == 0) cuml_no_heads = cumsum(trials 1) cuml_no_tails = cumsum(trials == 0) Simulate a fair coin toss over 1000 trials Plot the frequency of heads and the frequency of tails per trial. b. Plot the relative frequency of heads and the frequency of tails per trial. c. Simulate an unfair coin toss with P(X = H) = 0.7, P(X = T) = 0.3 .
