Question

2. Consider a coin which shows heads with probability $p$ and tails with probability $1 - p$. We toss the coin $N$ times, where $N$ is random with $P[N = k] = e^{-lambda} frac{lambda^k}{k!}$ for all $k in mathbb{N}_0 = {0, 1, 2, ...}$. All tosses are independent of each other. Denote by $X$ the number of heads tossed, and by $Y$ the number of tails tossed. Decide if $X$ and $Y$ are independent random variables. Give a reason for your answer.

Consider a coin which shows heads with probability p and tails with probability 1 - p. We toss the coin N times, where N is random with P[N = k] = e^(-̄λ) λ^k/k! for all k ∈ N0 = {0, 1, 2, ...}. All tosses are independent of each other. Denote by X the number of heads tossed, and by Y the number of tails tossed. Decide if X and Y are independent random variables. Give a reason for your answer.
