Determine if events A and B are independent. P(A) = 9/20 P(B) = 7/10 P(A and B) = 63/200
A) Dependent B) Independent

P(A) = 7/10 P(B) = 7/10 P(A and B) = 21/40
A) Independent B) Dependent

Independent

Dependent

Step-by-step explanation:

Two events are independent of each other when you can mulitply them and get their intersect

we can can see that

9/20*7/10= 63/200 so these events are independent

For number 2

7/10*7/10≠ 21/40 so these events are dependent

the transverse axis of a hyperbola is the line that contains the two vertices and the two focuses.

in this example (hyperbola of equation x^2/2 - y^2/4 = 1), the transverse axis is the  x-axis  .
