if you draw one of 24 slips of paper numbered from 1-24. what is the probability of drawing a number divisible by 3?...I just need some help remembering
how many numbers between 1 and 24 are divisible by 3
favourable events=3,6,9,12,15,18,21,24 number of favourable events=8 total no. of events=24 p=favourable /total events
nice explaining surjithayer :)
so then with the information stated how would you begin?
oh you mean to divide?
the answer would be 3?
there are 8 numbers between 1 and 24 that are divisible by 3. And there are a total of 24 slips of paper. So it is 8/24 which reduces to what ?
3
not 3
8/24 reduces to what ?
\[please note probability is always \le 1\]
8 goes into its self 1 time and 8 goes into 24 3 times
exactly.....so it is 1/3 probability of drawing a slip of paper with a number divisible by 3.
ok...I obviously didn't pay attention in class...thanks
no problem :)
