How are the graphs of these ellipses similar and how are they different?

The explanation how are the graphs of the ellipses
Answer to Problem 1RE
Solution:
Each equation represents an ellipse with a vertical major axis of length 30 units and horizontal minor axis of length 20 units. However, the first equation represents an ellipse centered at
Explanation of Solution
Given Information:
The equations of ellipse are
Use the formula,
If in the ellipse, the major axis is
Where; the center is
Consider the provided ellipses:
The First Ellipse
So, the ellipse has its center at
Length of the major axis is
The Second Ellipse:
The ellipse has its center at
Length of the major axis is
The graphs of the equations are sketched as:
Each equation represents an ellipse with a vertical major axis of length

They are playing a game where they randomly pick a card out of the hat four times, with replacement. Amy thinks that the probability of getting exactly two aces in four picks is equal to the probability of not getting exactly two aces in four picks. Samiha disagrees. She thinks that the probability of not getting exactly two aces is greater. The sample space of possible outcomes is listed below. A represents an ace, and K represents a king.
