Question

Ten percent of the population is left-handed. In a class of 100 students, write the binomial probability for the statement ?There are at most 12 left-handed students in the class.?
A) $\mathrm { P } ( \mathrm { x } \leq 12 )$
B) $P ( x < 12 )$
C) $\mathrm { P } ( \mathrm { x } = 12 )$
D) $\mathrm { P } ( \mathrm { x } \geq 12 )$

Quizplus · Accepted Answer

The binomial probability of "at most 12 left-handed students" includes all outcomes from 0 to 12 left-handed students, which is represented by $P(x \leq 12)$.

Ten Percent of the Population Is Left-Handed P(x≤12)\mathrm { P } ( \mathrm { x } \leq 12 )P(x≤12)

Ten Percent of the Population Is Left-Handed $\mathrm { P } ( \mathrm { x } \leq 12 )$
