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.
now, there are two possible angles for that tangent... however, let's look at our a,b components.
"a" is negative whilst "b" is positive, so is not 0 then, thus
