Step-by-step explanation:
<u>Addition Law for Probability</u>
![\sf P(A \cup B)=P(A)+P(B)-P(A \cap B)](https://tex.z-dn.net/?f=%5Csf%20P%28A%20%5Ccup%20B%29%3DP%28A%29%2BP%28B%29-P%28A%20%5Ccap%20B%29)
Given:
![\sf P(A)=\dfrac{1}{3}=\dfrac{3}{9}](https://tex.z-dn.net/?f=%5Csf%20P%28A%29%3D%5Cdfrac%7B1%7D%7B3%7D%3D%5Cdfrac%7B3%7D%7B9%7D)
![\sf P(B)=\dfrac{2}{9}](https://tex.z-dn.net/?f=%5Csf%20P%28B%29%3D%5Cdfrac%7B2%7D%7B9%7D)
![\sf P(A \cup B)=\dfrac{4}{9}](https://tex.z-dn.net/?f=%5Csf%20P%28A%20%5Ccup%20B%29%3D%5Cdfrac%7B4%7D%7B9%7D)
Substitute the given values into the formula and solve for P(A ∩ B):
![\implies \sf P(A \cup B) = P(A)+P(B)-P(A \cap B)](https://tex.z-dn.net/?f=%5Cimplies%20%5Csf%20P%28A%20%5Ccup%20B%29%20%3D%20P%28A%29%2BP%28B%29-P%28A%20%5Ccap%20B%29)
![\implies \sf \dfrac{4}{9} = \sf \dfrac{3}{9}+\dfrac{2}{9}-P(A \cap B)](https://tex.z-dn.net/?f=%5Cimplies%20%5Csf%20%5Cdfrac%7B4%7D%7B9%7D%20%3D%20%5Csf%20%5Cdfrac%7B3%7D%7B9%7D%2B%5Cdfrac%7B2%7D%7B9%7D-P%28A%20%5Ccap%20B%29)
![\implies \sf P(A \cap B) = \sf \dfrac{3}{9}+\dfrac{2}{9}-\dfrac{4}{9}](https://tex.z-dn.net/?f=%5Cimplies%20%5Csf%20P%28A%20%5Ccap%20B%29%20%3D%20%5Csf%20%5Cdfrac%7B3%7D%7B9%7D%2B%5Cdfrac%7B2%7D%7B9%7D-%5Cdfrac%7B4%7D%7B9%7D)
![\implies \sf P(A \cap B) = \sf \dfrac{3+2-4}{9}](https://tex.z-dn.net/?f=%5Cimplies%20%5Csf%20P%28A%20%5Ccap%20B%29%20%3D%20%5Csf%20%5Cdfrac%7B3%2B2-4%7D%7B9%7D)

Answer:
a, b, and d
Step-by-step explanation:
Answer: n= 32
Jakes started with 32
Step-by-step explanation:
Let n represent the initial integer.
Step 1: take the reciprocal.
Reciprocal of n = 1/n
Step 2: double the number obtained in step 1
= 2×1/n = 2/n
Step 3: take the reciprocal of the number obtained in step 2.
Reciprocal of 2/n = n/2
Since he ended up with 16
n/2 = 16
n = 2×16 = 32
Answer:
33. The sheep pen is 16 square yards
Step-by-step explanation:
You can divide the rhombus inside into two triangles. Each triangle has a base of 4 yards and height 4 yards.
Area of triangle: A = 0.5*b*h = 0.5(4)(4) = 8
Since there are 2, then 2*8 = 16 square yards.
