The correct answer is the likelihood that the probability project can be finished in 21 days, assuming normal distribution applies, is roughly 90%.
Along the critical route, a project is anticipated to take 15 months with a standard variation of 3 months. The likelihood of finishing project A in 15 months is 100%. Over a year represents 84%. Correct Choice 50% within 15 months Proper Option D 12 months or more is 16% The phrase "at least in the likelihood" denotes that all possibilities greater than the specified probability exist. As opposed to this, the phrase "at most in the likelihood" refers to all probabilities that are lower than the stated probability. As a result, we may argue that at least means minimum and at most indicates maximum.
