Answer: Q= -31
Step-by-step explanation:
Using complementary events, considering a 
probability of drawing a red marble, the probability of not drawing a red marble is of 
.
<h3>What are complementary events?</h3>
They are mutually exclusive events which have the sum of their probabilities as 1.
In this problem, we consider that there is a probability of drawing a red marble, and since drawing a red marble and drawing a non-red marble are complementary events, we have that:
The probability of not drawing a red marble is of .

Say it out loud it goes, RS, ST.
If you put RS and ST together the angle RTS
Hey there!
2x + 7 = 27
2x = 20
x = 10
3x + 1 = 28
3x = 27
x = 9
The values for both of these equations are 9 and 10; therefore, the answers are not equivalent.
I hope this helps!
