I have a query here. For the case 4 when 4 tosses are made shouldn’t the probability be $\frac{1}{8}$ instead of $\frac{1}{16}$ because at 4th toss, it be might be HHHT, or HHHH(he makes atmost 4 tosses)? Please guide.

The diameters of $10000$ ball bearings were measured. The mean diameter and standard deviation were found to be $10mm$ and $0.05mm$ respectively. Assuming Gaussian distribution of measurements, it can be expected that the number of measurements more than $10.15mm$ will be (A) 230 (B) 115 (C) 15 (D) 2
