How many times would a coin have to show heads in 50 tosses to have an experimental probability of 20% more than the theoretical probability of getting heads? 10 25 35 45

35. The theoretical probability of getting head is 50% for a fair coin. Since the experimental(the actual) probability is 20% more, the experimental probability is 50+20=70%. 70% percent of the coin tosses are heads. 50*70%=35.
