Now assume that the times listed are only the expected times instead of being fixed times. Is the probability of being finished in fewer than $27$ weeks more or less than $50\%?$

The probability is more than $50\%$ because $27$ weeks is less than the expected time for the project.

The probability is more than $50\%$ because $27$ weeks is more than the expected time for the project.

The probability is less than $50\%$ because $27$ weeks is less than the expected time for the project.

The probability is less than $50\%$ because $27$ weeks is more than the expected time for the project.A project network is shown in the figure.
