Answer 2

Answer:

19 over 20

Step-by-step explanation:

we have asked to find out the probability of non defective screw drivers

so ,

total screw drivers in a box = 500

no of defective screw drivers = 25

non defective screw drivers = 500-25

                                              = 475

for calculating the probability = no of favourable outcomes

                                                      total no of outcomes

we will divide all

therefore ,                  

                   475

                    500    

when we cut them on the table of 5  the answer will be 95

                                                                                            100

again we will cut them on the table of 5

so the final ans will 19 over 20 or 19

                                                          20
