The correct answer is option B. i.e. the experimental probability is 3% greater than the theoretical probability
The theoretical Outcomes are: HH HT TH TT
Then, the probability of getting HH = 1/4 = 0.25 = 25%
Now, Experimental Outcomes : HH=28 HT=22 TH=34 TT=16
Total number of outcomes = 28+22+34+16 = 100
Then, the probability of getting HH = 28/100 = 0.28 = 28%
Thus, the experimental probability is 3% greater than the theoretical probability
