I believe answer choice C is the answer. You would solve whatever is inside of the parentheses first because of PEMDAS.
1) Expression
2) Equation
3) Expression
4) Equation
Bob the numerator and denominator are divisible by 3 so the simplified fraction would be 9/17
Answer:
0.25
Step-by-step explanation:
This is the question on conditional probability
Let A - the quadrilateral has four right angles
B - the quadrilateral has four equal side lengths
Required probability = P(B/A)
By definition of continuous probability


P(A) = 
Hence given probability =
