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
