The table below shows the results of flipping two coins. how does the experimental probability of getting HH compare to the theo
retical probability of getting HH? Outcome: HH HT TH TT
# of times tossed: HH=28 HT=22 TH=34 TT=16
A. the experimental probability is 3% greater than the theoretical probability
B. the theoretical probability is 3% greater than the experimental probability
C. the experimental probability is 7% greater than the theoretical probability
D. the experimental probability is equal to the theoretical probability
The correct answer is option B. i.e. the experimental probability is 3% greater than the theoretical probability<span>
The </span>theoretical Outcomes are: HH HT TH TT Then, the probability of getting HH = 1/4 = 0.25 = 25%
Now, Experimental Outcomes : <span>HH=28 HT=22 TH=34 TT=16 Total number of outcomes = 28+22+34+16 = 100 </span>Then, the probability of getting HH = 28/100 = 0.28 = 28%
Thus, <span>the experimental probability is 3% greater than the theoretical probability</span>
You can't divide 56 equally with 6, so you have to find the nearest dividable number. That number is 54. 54 divided by 6 is 9, which eliminates option C and D. Since 56-54 (the number we took) is 2, the answer is B.
