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

priyanka saggu · Accepted Answer

Number of bolts = 50 and number of nuts= 150

Total number of items = 50 +150 = 200

Number of bolts rusted = 25

Number of nuts rusted = 75

So, total number of items rusted = 25 + 75 = 100

P(picking item which is rusted) = 100200

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.
