Question

Of total of 600 bolts 20% too large amd 10 % too small the remaining are consider to be suitable. If a bolt is selected at random what is the probability that it will be suitable

Answer 1

Answer:

60 will be your answer by my side

Answer 2

Step-by-step explanation:

Given Of total of 600 bolts 20% too large and 10 % too small the remaining are consider to be suitable. If a bolt is selected at random what is the probability that it will be suitable

• Given Of total of 600 bolts 20% too large and 10 % too small the remaining are consider to be suitable. If a bolt is selected at random what is the probability that it will be suitable
• Now out of 600 too large bolts are 20% = 20/100 x 600
•                                                                 = 120
• Also out of 600 bolts too small bolts are 10% = 10/100 x 600
•        = 60
•                                 So 120 + 60 = 180
•       So suitable bolts will be 600 – 180 = 420
• Therefore we have
•        Probability = Favourable outcomes / total number of outcomes.
•                                                     = 420 / 600
•                                                      = 42 / 60
•                                                     = 7/10
•  OR
•      
•       20% + 10% = 30% are non-suitable
•     So the rest 70% will be suitable = 7/10
