Consider three events A, B and C with following properties.
lisov135 [29]
By the inclusion/exclusion principle,

\mathbb P(D)=\mathbb P(A\cup B\cup C)
\mathbb P(D)=\mathbb P(A)+\mathbb P(B)+\mathbb P(C)-\bigg(\mathbb P(A\cap B)+\mathbb P(A\cap C)+\mathbb P(B\cap C)\bigg)+\mathbb P(A\cap B\cap C)
\mathbb P(D)=\dfrac14+\dfrac16+\dfrac14-\dfrac39+\dfrac1{13}
\mathbb P(D)=\dfrac{16}{39}\neq1

So the union of A, B, and C does not constitute the entire sample space.

Question 25
AysviL [449]

Answer:

120

Step-by-step explanation:

First, you have to calculate the money that Seth would spent if he goes to 30 movies if his father gets the summer movie pass by adding up the cost of the pass plus the result of multiplying the cost per movie with the pass for the number of movies:

30+(3*30)=30+90=120

Second, you need to calculate the money that Seth would spent if he goes to 30 movies without the pass by multiplying the normal price per movie for the number of movies:

8*30=240

Third, you need to find the difference between both costs:

240-120=120

According to this, the answer is that if Seth plans to go to 30 movies this summer, he would save 120.

The diameter of a circle is 14 in. Find its area in terms of <br> π<br> π.
maksim [4K]

Answer:

49π in²

Step-by-step explanation:

Step 1: Find the radius.

  • To find radius given diameter, just divide the diameter by 2: \frac{14}{2}
  • 14/2 = 7, so the radius is 7.

Step 2: Apply area of circle formula.

  • The formula to find the area of a circle is πr², where r = radius.
  • Now, plug in the value of r: π(11)².

Step 3: Simplify.

  • π(11)²
  • π(121)
  • 121π

Since we're finding the area in terms of pi, we don't have to multiply 121 by pi, so the answer is 49π in².
