The probability of not drawing a black marble is 4/5
The probability of drawing a red marble is 3/10
<h3>What are the probabilities?</h3>
Probability determines the odds of the occurrence of a random event. The probability the event occurs is 1 and the probability that the event does not occur is 0.
Probability of not drawing a black marble = total marbles that are not black / total number of marbles
(5 + 3) / (5 + 3 + 2) = 8/10 = 4/5
The probability of drawing a red marble = total number of red marbles / total number of marbles
= 3/10

Answer:
(-2,9) ,(4,-3)
Step-by-step explanation:
Given the expression 2x+y=5
We are required to look for values of x and y such that when substituted into the given expression will result in the number 5
The Pairs are (-2,9) ,(4,-3)
Let us plug in the values to check
1. (-2,9)
2(-2)+9=5
-4+9=5
5=5 true
2. (4,-3)
2(4)+(-3)=5
8-3=5
5=5 true
Answer:
Step-by-step explanation:
first add 3+5 = 8
then multiply 8 times x and 8 times -1
which is 8x-8
