Makayla is teaching Rodney how to construct a square inscribed in a circle. Makayla says Rodney should draw diameter AB, and the

n use a compass and a straightedge to find chord CD that bisects diameter AB. Makayla also tells Rodney he should use a straightedge to draw the four chords that make up the square: chords AC, AD, BC, and BD. What error, if any, is Makayla making in her instructions to Rodney? A. Chord CD must not only bisect but must also be perpendicular to diameter AB. B. Chord AB can be any chord of the circle, not just a diameter. C. The chords that make up the square are chords AB, BC, CD, and DA. D. Makayla made no errors in her instructions to Rodney.

Events A and B have probabilities such that P(A) = 0.3, P(B) = 0.25, P(M ∪ N) = 0.425, and P(M ∩ N) = 0.075. Are events A and ev
nekit [7.7K]

Answer:

(C)Yes, because P(M) ∙ P(N) = P(M ∩ N)

Step-by-step explanation:

Two events A and B are independent if P(A)P(B)=P(A ∩ B)

Given events A and B such that:

P(A) = 0.3, P(B) = 0.25, P(A ∪ B) = 0.425, and P(A ∩ B) = 0.075

  • P(A)P(B)=0.3 X 0.25 =0.075
  • P(A ∩ B) = 0.075

Since the two expression above gives the same answer, they are independent.

<u>The correct option is C.</u>
