Answer with good high level explanation please

Suppose you had a choice of using one of three different branch prediction schemes:

I predict that each branch is never taken

II predict that each branch is always taken

III use a dynamic predictor that correctly predicts $90\%$ of the time

Scheme I has a one$-$cycle penalty for a misprediction.

Scheme II has a two$-$cycle penalty for a misprediction.

Scheme III has a three$-$cycle penalty for a misprediction.

What is the total number of penalty cycles incurred for each of these schemes by a

conditional branch instruction that executes $12000$ times and actually branches $60\%$ of

the time?

total penalty cycles for scheme $I=$

total penalty cycles for scheme $II=.$

total penalty cycles for scheme III$=$
