what is the probability that a survey student oppose legalization of marijuana?

Question

in a poll of 626 university students, 292 said that they were opposed to legalizing marijuana.

Answer 1

The probability of something is the answer you're looking for (i.e. that fits the criteria) divided by total possible answers.

 

You're looking for those opposed, which is 292.

The total possible is 262, since there's 626 total students in the survey.

 

Hence, P(opposed) = 292/626.

 

It is appropriate to leave it as a fraction and reduce it, or divide and get a decimal number.  Your instructor may prefer a specific format for the answer, and for rounding decimals.

Answer 2

Total students = 626

Student Opposing = 292

 

we'll solve this as a ratio to find out how it pens down;

 

626 : 292

 

2.143 : 1

 

≅ 2 : 1

 

so from this, 1 out of every 3 student opposed or would oppose the legalization of marijuana.
