Answer 1

The question involves calculating the probability of early completion time using project management techniques like PERT or CPM, but lacks sufficient data for a precise answer.

Step-by-step explanation:

The question asks for the probability P(Te<23), which appears to be related to project management techniques such as PERT (Program Evaluation and Review Technique) or CPM (Critical Path Method). These methods involve statistical calculations to determine the likelihood of completing a project within a given time frame, incorporating activity durations which often follow a beta distribution. Given the absence of sufficient data in the question, a precise answer cannot be calculated. However, P(Te<23) refers to the probability that the early completion time of a particular event or activity is less than 23 units of time.
