2. What percent of rolling a 2<br><br><br> 3 probability of getting HH
faust18 [17]

<u>Answer:</u>

2. The correct answer option is 25%.

3. The experimental probability is 3% greater than the theoretical probability.

<u>Step-by-step explanation:</u>

2. We are given that a number cube is rolled 20 times out of which 5 times it lands on the number 2.

We are to find the experimental probability of getting the number 2.

P (2) = \frac{5}{20} \times 100 =\frac{1}{4} \times 100 = 25%

3. The theoretical Outcomes are: HH HT TH TT

So theoretical probability of getting HH = \frac{1}{4} \times 100 = 25%

Total number of outcomes = 28+22+34+16 = 100

So experimental probability of getting HH = \frac{28}{100} \times 100 = 28%

Therefore, the experimental probability is 3% greater than the theoretical probability.
