Please show me how this is calculated

**Question:** (FIB Question) Consider a branch that is not taken 100 times and taken once, what is the accuracy of an always taken branch predictor for that branch in percentage (write integer part only e.g., 50)? **Answer Box:** [ ] In this question, you're tasked with calculating the accuracy of an "always taken" branch predictor. This kind of predictor assumes that a branch will always be taken. Given that the branch is not taken 100 times and only taken once, you'd calculate the predictor’s accuracy based on its correct predictions. To find the accuracy: 1. Total number of branch evaluations = 100 not taken + 1 taken = 101. 2. Correct predictions by the "always taken" predictor = 1 (since it predicts "taken"). 3. Accuracy = (Correct predictions / Total evaluations) × 100% 4. Fill in the integer part of this percentage in the answer box.
