Question 555110: A manufacturer makes mobile phones. The manufacturer employs an inspector to check the
quality of its product. The inspector tested a random sample of the phones from a large batch
and calculated the probability of any phone being defective as 0.049. Ashmita buys two of the
phones made by the manufacturer. Find the probability that
i. Both mobile phones are defective.
ii. Exactly one of the mobile phones is defective

the probability of any phone being defective as 0.049. Ashmita buys two of the
phones made by the manufacturer.
---------
Find the probability that
i. Both mobile phones are defective.:::0.049^2 = 0.0024
------------------------------------------------------------
ii. Exactly one of the mobile phones is defective
Note: P(neither is defective) = 0.951^2 = 0.9044
Therefore: P(one is defective) = 1-(0.0024+0.9044) = 0.0932
