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 least 12 left-handed students in the class.?
A) $P ( x \geq 12 )$
B)P(x $\mathrm { P } ( \mathrm { x } < 12 )$
C) $P ( x > 12 )$
D) $\mathrm { P } ( \mathrm { x } \leq 12 )$

Quizplus · Accepted Answer

The correct choice is $P ( x \geq 12 )$ because it directly translates to the probability of having at least 12 left-handed students in the class.

Ten Percent of the Population Is Left-Handed P(x≥12)P ( x \geq 12 )P(x≥12)

Ten Percent of the Population Is Left-Handed $P ( x \geq 12 )$
