P(A/B) = P(A∩B) / P(B)
P(A/B) = (3/10) / (2/5) = 3/10 x 5/2 = 15/20 = 3/4
C I think I’m not sure because I’m stuck on it too
Answer:
Step-by-step explanation:
Represent Anita's age by a and Basilo's by b.
Then a = b - 4.5, and 3(a + 6) = 36 (where I have "invented" the value 3).
Substituting b - 4.5 for a in 3a + 18 = 36: 3(b - 4.5) + 18 = 36
Performing the indicated multiplication:
3b - 13.5 + 18 = 36, or
3b + 13.5 = 18, or
b = 18 - 13.5 = 4.5
Basilo is 4.5 years old, whereas Anita is 9 years old.

4y+yz is the correct answer
The picture in the attached figure
we have
arc XV = 68°∠YUV = 36°
we know that
The measure of the external angle is the semidifference of the arcs that it covers.
therefore
∠YUV =[arc VY-arc XV]/2
arc VY=[2*∠YUV]+arc XV----------> [2*36]+68---------> 140°
the answer is
the measure of arc VY is 140°
