In our example, event A is getting a blue candy, and P ( A) represents the probability of getting a blue candy with a probability of 4 9: P ( A) = 4 9. Also, event B is getting a blue candy second, but for that, we have two scenarios such as: If we chose a blue candy first, the probability is now 3 8. dictionary replace function in python

WebWe can also prove this identity algebraically, using the binomial theorem, $(a+b)^n=\sum_{k=0}^{n} {n \choose k} a^k b^{n-k}$. If we let $a=b=1$, we obtain $2^n=\sum_{k=0}^{n} {n \choose k}$. To show this identity, let's assume that we have an arbitrary set $A$ with $n+1$ distinct elements: $$A=\{a_1, a_2, a_3, ...,a_n,a_{n+1}\}.$$ …
