Answer:
Step-by-step explanation:
the total number of nuts and bolts together = 50 + 150 = 200
since it is given that half of it is rusted,
no. of bolts rusted = 50/2 = 25
no. of nuts rusted = 150/2 = 75
the total number of nuts and bolts that are rusted = 75 + 25 = 100
therefore the probability if it is chosen randomly = 100/200
= 1/2
