How necessary is Math senior year for college admissions??

We have a similar situation. My daughter finished Algebra 2 as a sophomore last year. This year she had a choice of taking Analysis/Trig or Probability/Statistics. Her guidance counselor and I agreed that she should take Statistics this year since she struggled quite a bit in algebra 2. We would revisit taking Analysis/Trig her senior year if a 4th year of math is needed for her college selections, possibly taking an Alg 2 refresher class over the summer.

Could Statistics be an option for implicitvagabond?

My daughter also has a 3.4 gpa and is targeting same caliber colleges. Has she been misguided? Should she have taken Analysis/Trig this year? It is not too late for her to switch.

Thanks
