There are 2 orange marbles, 3 green marbles, & 5 purple marbles
two consecutives draws <em>without</em> replacement
Orange first, green second
Orange/total = 2/10, or 1/5
green/total - 1 = 3/9, or 1/3
1/5(1/3) = 1/15
There is a 1/15 chance of <em>Orange first, green second</em>
Both marbles are purple
Purple/total = 5/10, or 1/2
Purple/total = 4/9, or <em>44% chance of both being purple</em>
first is purple, the next is anything but purple
purple/total = 1/2, or 50% chance
(everything - purple)/total = 5/10, or 50% chance
1/2(1/2) = 1/4, or 25% chance of <em>first purple, then anything but purple</em>
hope this helps

<em>Answer:</em>
<em>x=4 y=3</em>
<em>Step-by-step explanation:</em>
<em>rewrite the equations- y=x-1 2x-3y=-1</em>
<em>solve y=x-1 for y</em>
<em>y=x-1</em>
<em>sub for x-1 for y in 2x-3y=-1</em>
<em>2x-3y=-1</em>
<em>2x-3(x-1)=-1</em>
<em>-x+3=-1</em>
<em>-x+3+-3=-1+-3</em>
<em>-x=-4</em>
<em>divide both sides by -4</em>
<em>x=4</em>
<em>sub 4 for x in y=x-1</em>
<em>y=x-1</em>
<em>y=4-1</em>
<em>y=3</em>
