The QMplus-gremlins are mischievous creatures that cause computer problems. After careful research you observe that the number ofgremlins active each day is a random variable with Bin(3, 0.5) distribution. If no gremlins are active, the probability of QMplus failureis 0.15; if one gremlin is active the probability of QMplus failure is 0.3; if two or more gremlins are active the probability of QMplusfailure is 0.5. You conclude that the total probability of QMplus failure on a given day is(to two decimal places). Assumingthere is a failure, the probability no gremlins are active is(again to two decimal places).

After careful research you observe that the number of hackers active on each day is a random variable Bin(3,0.5) distribution. If no hackers are active, the probability of the website failure is 0.15; If one hacker is active the probability of the website failure is 0.3; if two or more hackers are active the probability of the website failure is 0.5. You conclude that the total probability of website failure on a given day is two decimal place). Assuming there is a failure, the probability no hackers are active is (to (to two decimal places).
