Answer:
I think its -1
Step-by-step explanation:
Im taking a quiz with the given question.
Total number of students = 10
As we have to find
P(A/B) = Probability( A when B has happend)
P(A/B)= P(A intersection B)/P(B)
According to given figure only yolanda and Rob are in both club
Therefore,P(A intersection B) 
Number of student in karate club =6
P(B)
P(A/B) 
Converting division into multiplication by reciprocating the term after division
P(A/B) 
On solving we get ,
P(A/B) 
P(A/B)
P(A/B) 
Given the equation of the parabola

The vertex of this parabola is placed at point (4,3).
If the equation of the parabola is
then

The coordinates of the parabola focus are

Therefore, the focus is placed at point (4,3,75).
Answer: option D, 0.75 in. above the vertex
