Question

Ten percent of the population is left-handed. In a class of 56 students, write the binomial probability for the statement ?There are at least 10 left-handed students in the class.?
A) $P ( x \geq 10 )$
B) $\mathrm { P } ( \mathrm { x } \leq 10 )$
C) $P ( x > 10 )$
D) $\mathrm { P } ( \mathrm { x } < 10 )$

Quizplus · Accepted Answer

The correct expression for the probability of having at least 10 left-handed students is $P ( x \geq 10 )$, which includes 10 and any number greater than 10.

Ten Percent of the Population Is Left-Handed P(x≥10)P ( x \geq 10 )P(x≥10)

Ten Percent of the Population Is Left-Handed $P ( x \geq 10 )$
