Question

it is known that a box of 800 electrical bulbs contain 36 defective bulbs one bulb is taken at random out of the box what is the probability that the bulb chosen is non defective​

Answer 1

Step-by-step explanation:

It is given that Total number of electric bulbs = 800 Defective bulbs = 36 So the number of non-defective bulbs = 800 – 36 = 764 We know that Probability that the bulb chosen is non defective = number of non-defective bulbs/ total number of bulbs By substituting the values Probability that the bulb chosen is non defective = 764/800 So we get Probability that the bulb chosen is non defective = 191/200

Answer 2

Answer:

probability of chosen of non defective bulbs is 191/200

Step-by-step explanation:

Total no. of bulbs=800

No. of defective bulbs=36

no. of non-defective bulbs=800-36=764

probability of non defective bulbs to total no. of bulbs=non defective bulbs/total no. of bulbs

                                                                                         =764÷800

                                                                                         =191/200
