Compute the overall total CPI for a pipelined processor that uses a branch predictor assuming the following:

- Branch outcomes are determined in the EX phase.

- Branch prediction is accurate 70% of the time.

- Branches are 10% of program instructions.

- Due to data hazards, non-branch instructions have an average CPI of 1.2.

Please explain how you got your answer. I get stuck after multiplying accuracy with occurence (0.7)(0.1) + 1.2? not sure where to go after that.
