Answer:
There is a 1/64 possibility.
Step-by-step explanation:
Since the probability of selecting student 1's number is 1/8 and then replacing it leaves us with still 8 numbers to choose from, so student 8's probability of being selected is also 1/8. Multiplying these two gives P=1/64, since (1/8)^2 = 1/64.

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
I think that it is 9 because 14-10=4 so 3+2+4=9 I’m not that sure tho let me know if I’m wrong
Answer:
The remaining interior angles of this triangle are 140º and 10º
Step-by-step explanation:
The sum of the interior angles of a triangle is always 180º.
A triangle has 3 angles. In this problem, we have one of them, that i am going to call A1 = 30º.
The sum of a interior angle with it's respective exterior angle is also always 180º.
We have that one of the exterior angles is equal to 40°. So it's respective interior angle is
40º + A2 = 180º
A2 = 180º - 40º
A2 = 140º
Now we have two interior angles, and we know that the sum of the 3 interior angles is 180º. So:
A1 + A2 + A3 = 180º
A3 = 180º - A1 - A2
A3 = 180º - 30º - 140º
A3 = 180º - 170º
A3 = 10º
