Actually I was not sure about the formula, that's why I posted the question with the work I have done so far. I am posting the right solution so that a student like me can benefit from it in the future The formula for my question is: average access time = (cache hit time x cache hit rate) + (cache miss rate)(RAM hit time x RAM hit rate)+ (cache miss rate)(RAM miss rate)(disk hit time)
BUT AGAIN I HAVE A QUESTION why we did not need to multiply disk hit rate at the end?Why it was not given in the question?
