Answer:
Step-by-step explanation:
To calculate probability, divide the number of events by the number of possible outcomes. In this example. there are 18 events (18 chips that aren't pink) and 22 outcomes (22 total chips). That means the probability is for not drawing a pink chip. Simplifying that gives you

Answer:
(4, 1)
Step-by-step explanation:
Since the first reflection is over the vertical line x=-3, the y-coordinate remains the same. The x-coordinate of A' will make the point (-3, 4) on the line of reflection be the midpoint between A and A':
(-3, 4) = (A +A')/2
2(-3, 4) -A = A' = (-6-(-7), 8 -4) = (1, 4)
The reflection over the line y=x simply interchanges the two coordinate values:
A'' = (4, 1)
