good, so whats the probability of achieving a test score of 2 or higher ?
anonymous
  • anonymous
88% ?
ganeshie8
  • ganeshie8
Excellent! lets get back to the main problem
ganeshie8
  • ganeshie8
you have 1000 students and you know that 88% of them are most likely to score 2 or higher
ganeshie8
  • ganeshie8
so you simply need to find 88% of 1000 to get the number of students that score 2 or higher
ganeshie8
  • ganeshie8
whats 88% of 1000 ?
anonymous
  • anonymous
do i divide them?
ganeshie8
  • ganeshie8
88% means 88 in every 100
ganeshie8
  • ganeshie8
so how many in 1000 ?
ganeshie8
  • ganeshie8
make a good guess, im sure u wil be right
anonymous
  • anonymous
i got 0.088?
ganeshie8
  • ganeshie8
0.088 students? haha are you planning to cut the students ? maybe forget the formulas. out of 100 students, if 88 students are good, then how many students will be good out of 1000 students ?
ganeshie8
  • ganeshie8
100 ---> 88 1000 --> ?
anonymous
  • anonymous
is it 880 by any chance?
ganeshie8
  • ganeshie8
Yes, aren't you sure ?
anonymous
  • anonymous
I added 88, 10 times... 😅
ganeshie8
  • ganeshie8
interesting, why ?
anonymous
  • anonymous
I could've multiplied it, but I didn't think of it, and bc if 100 = 88 and 100, 10 times is 1000 so I added 88 10 times..
ganeshie8
  • ganeshie8
Awesome! thats good thinking!
ganeshie8
  • ganeshie8
btw, 880 is correct
ganeshie8
  • ganeshie8
880 is 88% of 1000
