The internet worm “KLEZ” is the clear leader in the number of top malicious software instances. A recent survey reported KLEZ accounted for 53% of reported malicious instances. Suppose 7 malicious software instances are reported and assuming independence, calculate the probability (correct to 4 decimal places) that: (a) Exactly 3 were the internet worm KLEZ? (b) At least 1 was the worm KLEZ?
