Question
A box contains 50 bolts and 150 nuts. On checking the box, it was found that half of the bolts and half of the nuts are rusted. If one item is chosen at random, find the probability that it is rusted.​

Answer 1

Answer:

No. of rusted nuts=1/2×150

=75

No. of rusted bolts=1/2×50

=25

No. of rusted things=75+25=100

Total no. of things=150+50=200

Required probability=(100/200*100)% =50%
