Which of the speeds $v$ listed below is the lowest speed where the probability of a gas molecule having that speed is negligible compared to that for $v=v_{p}$ ("negligible" meaning less than $1 / 100$ of its value at $v=v_{p}$ ).
A) $v \approx 0.2 v_{p}$
B) $v=2 v_{p}$
C) $v=3 v_{p}$
D) $v=5 v_{p}$

The Maxwell-Boltzmann distribution describes the distribution of speeds of particles in a gas. The probability of finding a particle at a speed far from the most probable speed $v_p$ decreases exponentially. At speeds much higher than $v_p$, such as $5v_p$, the probability of finding a particle at that speed becomes negligible, much less than 1/100 of its value at $v_p$.
