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?

Assume that when adults with smartphones are randomly selected, 53% use them in meetings or classes. If 10 adult smartphone users are randomly selected, find the probability that at least 3 of them use their smartphones in meetings or classes. The probability is 0.0905 (Round to four decimal places as needed.)
A survey showed that 79% of adults need correction (eyeglasses, contacts, surgery, etc.) for their eyesight. If 15 adults are randomly selected, find the probability that at least 14 of them need correction for their eyesight. Is 14 a significantly high number of adults requiring eyesight correction? The probability that at least 14 of the 15 adults require eyesight correction is nothing. (Round to three decimal places as needed.)
