The probability that a student chosen at random isn't in the drama club or the sports team is 10/31.
What is the probability?Probability refers to a possibility that deals with the occurrence of random events.
The probability of all the events occurring need to be 1.
P(E) = Number of favorable outcomes / total number of outcomes
Let's denote students in D = in the drama club , S = in a sports team
P(D) = 70/310
P(S) = 190/310
P(D and S) = 50/310
P(D or S) = P(D) + P(S) - P(D and S)
P(D or S) = 70/310 + 190/310 - 50/310
P(D or S) = 210/310 = 21/31
P(neither D nor S) = 1- 21/31
P(neither D nor S) = 10/31
The probability that a student chosen at random isn't in the drama club or the sports team is 10/31.

Jerry solved the equation 2x-4=20 by adding four 1-tiles to each side. Explain why Jerry's method works.
Answer:
Kindly check explanation
Step-by-step explanation:
Given the equation : 2x-4=20
By adding 4 1 - tiles to each side, this will eleminate the constant term on the left hand side where the Coefficient we wish to solve for lies. Hence, the same exact treatment given to data on the right hand side is done to the data in the left. Hence, the method will work as it will give ;
2x - 4 = 20
2x - 4 + 4 = 20 + 4
2x = 24 ( constant eliminated)
x = 24/4
x = 6

Answer:
142.5 in^2
Step-by-step explanation:
First, find the area of the rectangle
19*10= 190
Now find the area of the triangle
A=1/2bh
A=1/2(19)(10-5)
A=47.5
Since we need the shaded region, subtract the triangle area from the rectangle area
190-47.5=142.5
How do I solve this?
I have the answer but what is the step-by-step explanation.
-7 = 1 + 2/3n
Subtract 1 from both sides:
-8 = 2/3n
Multiply both sides by 3:
-24 = 2n
Divide both sides by 2:
N= -12
Answer:
n=-12
Step-by-step explanation:
Okay this isn't to hard first in the equation you must subtract 1 from both sides
So this: -7=1+2/3n
Becomes This: -8=2/3n
Then I divided by 2 on both sides to get:-4=1/3n
Then I multiplied by three to get -12=n
