Question

A box contains 70 bolts and 130 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:

probablity = $\frac{1}{2\\}$

Step-by-step explanation:

Total no. of things in box=bolts +nuts=70+130=200

half of them are rusted , so no. of rusted nuts and bolts=200/2=100.

propability=no.of rusted nuts and bolts/total no. of nuts and bolts=100/200=1/2.

Therefore , propability that it is rusted =1/2 or 0.5.
