Convolutions
A convolution of two probability distributions is the probability distribution of the sum of two independent random variables that are distributed according to these distributions.
The convolution of two distributions can be constructed with convolve or its Unicode alias ⊕.

d1 ⊕ d2Convolve two distributions and return the distribution corresponding to the sum of independent random variables drawn from the underlying distributions.
The Unicode operator ⊕ can be typed by \oplus<tab>.
Currently, the function is only defined in cases where the convolution has a closed form. More precisely, the function is defined if the distributions of d1 and d2 are the same and one of
