Question

2. What percent of rolling a 2


3 probability of getting HH

Answer 1

2. The correct answer option is 25%.

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

Explanation:

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) =
`(5)/(20) * 100 =(1)/(4) * 100` = 25%

3. The theoretical Outcomes are: HH HT TH TT

So theoretical probability of getting HH =
`(1)/(4) * 100` = 25%

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

So experimental probability of getting HH =
`(28)/(100) * 100` = 28%

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