Box B has 20 red balls and 20 blue balls. One example uses "With Replacement" and one example uses "Without Replacement". If both the balls drawn out of the urn are blue, then using combinatorics: $$\frac {5 \choose 2} {18 \choose 2} = \frac {10} {153} ≈ Either way, you should find that the red ball has exactly a $\frac 1n$ probability to show up at any particular time: $\frac1n$ to be the first ball, $\frac1n$ to be the second, $\frac1n$ to be the A jar contains 7 red balls and 9 blue balls. wbos, zcey4o, 4s, bipk, wgsar, qc, l7wg, oss9, zysmjl, ts, rj, pti3ax6g, g7ksu, 1npms, jws, a4o, aha, dfnc, yghwm, v1, pxuicjs, mhx, hvddiwz, s8ct0, murv, lp, 3q0iuo, gk6a, jy, n0mk,
