Answer: Probability that the racket is wood or defective is 0.57.
Step-by-step explanation:
Since we have given that
Number of wood tennis rackets = 100
Number of graphite tennis rackets = 100
Total rackets = 100+100 = 200
Number of defected wood tennis rackets = 6
Number of defected graphite tennis rackets = 14
Total defective = 6+14 = 20
We need to find the probability that the racket is wood or defective.
So, Probability that the racket is wood or defective is given by
P( wood or defective) = P( wood) + P(defective) - P(Wood and defective)
Let A be the event for wood.
Let B be the event for defective.
Hence, Probability that the racket is wood or defective is 0.57.
