Answer:
"When applying the special rule of addition for mutually exclusive events, the joint probability is <u>0</u>."
Step-by-step explanation:
Mutually exclusive events are those events that cannot occur at the same time.
That is, if events <em>A</em> and <em>B </em>are mutually exclusive then their joint probability is 0.
The addition rule of probability is:
P (A or B) = P (A) + P (B) - P (A and B)
If A and B are mutually exclusive then, P (A and B) = 0.
Thus, the complete statement is:
"When applying the special rule of addition for mutually exclusive events, the joint probability is <u>0</u>."
Answer: 76.35in²
Step-by-step explanation:
Circumference of a circle = 2πr or πd , while area is πr².
To find the area we must first of all find the radius if the circle using any of the formula above.we then equate 31 to 2πr and then solve for r.
31 = 2πr , where π = 3.142 or 22/7
r = 31/2 x 3.142
= 31 /6.284
= 4.93in
To find the area, substitute for r in the formula above,
Area = πr²
= 3.142 x 4.93²
= 3.142 x 24.30
= 76.35in².

The calculator is correct haha, You're welcome.
Answer: The hundred-thousandth place
The area of a sector is = r(theta) with r radius and central angle theta being in radians, not degrees.
