comment Deriving the Doob Meyer decomposition of a Sub Martingale using Ito's
The representation you obtained $X_t = \int_0^t \left(2 + 15 B_s^4\right) \mathrm{d}s + 6 \int_0^t B_s^5 \mathrm{d}B_s$ is correct.

comment Probability of a random point $(U_1,U_2, \cdots, U_n)$ with $U_j \sim \operatorname{Unif}(-1,1)$ being in unit sphere in $\mathbb{R}^n$
Please do, and also please accept it, perhaps waiting for a few days for constructive suggestions.

comment Probability that rolling X dice with Y sides and summing the highest Z values is above some value k
The only way of doing it in R would be through simulations and simulation you can write in Python, R or many other freely available packages.

Suppose an exploding dice roll first resulted in 10, and then in 3, am I correct in concluding that its score equals 13?
