Probability Factor Solution

STEP 0: Pre-Calculation Summary
Formula Used
probability_factor = (Scheduled time-Mean time)/Standard Deviation
Z = (Ts-te)/σ
This formula uses 3 Variables
Variables Used
Scheduled time - Scheduled time is the time which is made as per the experience and practice by the creator of project. (Measured in Day)
Mean time - Mean time, also called as expected time is the time needed to complete an activity. (Measured in Day)
Standard Deviation- The Standard Deviation is a measure of how spread out numbers are.
STEP 1: Convert Input(s) to Base Unit
Scheduled time: 20 Day --> 1728000 Second (Check conversion here)
Mean time: 20 Day --> 1728000 Second (Check conversion here)
Standard Deviation: 40.83 --> No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
Z = (Ts-te)/σ --> (1728000-1728000)/40.83
Evaluating ... ...
Z = 0
STEP 3: Convert Result to Output's Unit
0 --> No Conversion Required
FINAL ANSWER
0 <-- Probability factor

What is an Event and an Activity?

An event represents the accomplishment of some task. In a network diagram, beginning and ending of an activity are represented as events. Each event is represented as a node in a network diagram. An event does not consume any time or resource. Each network diagram starts with an initial event and ends at a terminal event. An activity is a physically identifiable part of a project, which consumes both time and resources. Activity is represented by an arrow in a network diagram. The head of an arrow represents the start of activity and the tail of arrow represents its end. Activity description and its estimated completion time are written along the arrow.
