An indoor scene depicts a white surface, likely a whiteboard, covered with handwritten mathematical equations and text. The writing is primarily in blue ink, with some green ink visible on the right side. On the left side of the whiteboard, the word "Binomial" is written at the top. Below it, the notation "$X \sim B(n, p)$" is present. Further down, the binomial probability mass function is written as "$P(x=x) = (n C x)(p^x)(q^{n-x})$". Below this, the relationship "$p + q = 1$" is visible, followed by "$p \to Success$" and "$q \to Fail$". On the right side, faint green writing includes partial equations, appearing as "$X \sim B($" and "$P(x$". The whiteboard surface exhibits minor smudges and reflections, particularly noticeable towards the bottom and right side. No individuals or specific objects beyond the whiteboard and its markings are visible. The image does not visually depict the city of San Bernardino Tlaxcalancingo, Mexico; it shows an abstract indoor environment focused on mathematical content.
