    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
