Question

g A group of people were asked if some psychics can help solve murder cases. 175 responded "Yes", and 474 responded "To". Find the probability that if a person is chosen at random, the person believes some psychics can help solve murder cases.

Answer 1

Answer:

0.2696

Step-by-step explanation:

Number of People who responded Yes=175

Number of People who responded No=474

Total Number of Respondents=175+474=649

We want to determine the Probability that a person chosen at random believes that psychic can help solve murder cases.

Now,

[TeX]Probability=\frac{Number of Possible Outcome}{Total Number of Outcomes}[/TeX]

Number who believe psychic can help solve murder cases=175

Total Number=649

Therefore:

P(a person chosen at random person believes some psychics can help solve murder cases) = [TeX]\frac{175}{649}=0.2696[/TeX]
