Answer:
Question 1: 4/5 or %80
Question 2: 7/10 or %70
Step-by-step explanation:
<u>Step 1: Find the total amount of marbles</u>
5 + 2 + 3
<em>10</em>
<em />
<u>Step 2: Find the probability of not drawing a black marble</u>
Add the total amount of marbles that are not black
5 + 3
<em>8</em>
<em />
Now find the probability:
8/10
4/5 or %80
Answer: 4/5 or %80
<u>Step 3: Find the probability of not drawing a red marble</u>
Add the total amount of marbles that are not red
5 + 2
<em>7</em>
<em />
Now find the probability:
7/10 or %70
Answer: 7/10 or %70
P= 4 and -3
Move all the terms to the left side and set equal to zero. Then set each factor to zero.
check the picture below.
so, when we have a line from a 90° angle running perpendicular to the opposite side, like in this case, we end up with three similar triangles, a large one containing the other two, a medium and a small one.
now, using the sides proportions as you see there, of the small and large one, we get that much.
