PLS CAN YOU HELP ME

TO EXPRESS IN TRIGGER THE FOLLOWING QUTASION

Remaining Goal Expectation = Initial Expectation * Proportion of Time Remaining ^ 0.85

So as an example, if a side has an initial goal expectation of 1 for the entire game, when half of the match has elapsed, the remaining average goal expectation is given by:

1*(0.5^0.85) =0.55
