Jericho is doing a quick survey for his high school newspaper. He hands out a simple index card to 100 seniors in his high schoo
l and asks them to simply drop it in a box left near the gymnasium. The card has no place for a name or identifying information. It simply says "In the past year, have you been drunk even one time?" The student simply has to check "yes" or "no." If Jericho’s classmates are like most U.S. seniors, about ____ of them will check "yes." Quizlet
From research among high school students in the US, it was discovered in 2017 by US Centre for Disease Control and Prevention Agency(USCDC), that around 57.8% of high school students have drank alcohol in the previous 1 year.
Now, applying it to this question, since the survey is done among 100 seniors, the most modest probability would likely be 50% which represents 50 people out of the 100 surveyed that will likely check yes
Well you need to find a common denominator which 30 is the closest one. 5/6 becomes 25/30, 9/10 becomes 27/30. 27/30+ 25/30 = 52/30. To simplify that you divide by 2 to get 26/15. It is no longer divisible to a whole number after that point.
