Answer:
Option b
Step-by-step explanation:
Given that Mrs. Gomes found that 40% of students at her high school take chemistry
since each student is independent of the other, we can say
X no of students who take chemistry is binomial with p = constant proba = 0.40
n = no of trials = no of students surveyed =12
Required probability = prob atmost 4 students take chemistry
=
Substituting we get the cumulative probability
as
0.4382
round off to 0.438
Option b is correct answer
