Answer:
A
Step-by-step explanation:
observe
x² + 12x + y² + 10y = –45
add 36 + 25 on both side
x² + 12x + 36 + y² + 10y + 25 = –45 + 36 + 25 = 16
(x + 6)² + (y + 5)² = 16

n is the fixed number of trials. x is the specified number of sucesses. N - X is the number of failures. P is the probablity of success on any given trail. 1 - P is the probabilty of failure on any given trial.
These probabilities hold for any value of X between 0 (lowest number of possible successes in n trials) and n (highest number of possible successes).
