What was the answer to that probability Q in the jan 28 test

Test Preparation
1

<p>it was a grid in. and I put down 1/5</p>

2

<p>I think it was 5/9.</p>

3

<p>I confirm 5/9.</p>

4

<p>ohh ****</p>

<p>anyone wanna tell me how they got that, and how to get better @ SAT probability...(thats my one weakness and I thoguht I studied enough for it)</p>

<p>thanks</p>

5

<p>I didn't take the test, but if you tell me what it is I'll give you a solution.</p>

6

<p>there were 2 sets of numbers which I believe were {4,5,6} and {10,11,12}
The problem asked to take the products of one number from each set and determine what the probability was that the number was divisable by 5.</p>

<p>so 4(10)=40 4(11) = 44 4(12) = 48
5(10) = 50 5(11) = 55 5(12) = 60
6(10) = 60 6(11) = 66 6(12) =72
so 40, 50, 55, 60, 60 are divisible by 5 out of 9 choices.</p>

<p>5/9</p>

7

<p>That makes me feel good I got it right :)</p>

8

<p>i think i put 4/9 haha...im so mad. i dont remember, maybe it was 5/9. i just remember saying 1 from the 4, 2 from the 5, and 1 from the 6...which is retarded since of course 5 will go into all 3! hopefully i just remember wrong</p>

9

<p>5/9 for sure.</p>
