The problem above can be shown on a tree diagram as shown below
Question a)
Let C represents the five-star recruit who chooses one of the best three conferences
Let S represents the scholarship offer
P(C∩S) = 0.75×0.93 = 0.6975
Question b)
P(C'∩S) = 0.75×0.07 = 0.0525
Question c)
The two events are independent because it is possible for the events to happen in any order and one event's outcome does not affect the other event's.

Answer:
63.6cm²
Step-by-step explanation:
Area of square = 81
Side of square =
= 9
-----------------------------------------
diameter of circle = 9
radius of circle = 9 ÷ 2
= 4.5
area of circle = πr²
= π (4.5)²
= 63.6172512
≈ 63.6 cm²
