Answer:
The probability that at least one student majors in accounting=0.3×0.3×0.3=0.027
Explanation:
<em>Step 1: Determine the number of accounting majors in a business</em>
N=P×S
where;
N=number of accounting majors
P=probability of accounting majors
S=sample size
This can also be written as;
Number of accounting majors=probability of accounting majors×sample size
In our case;
Number of accounting majors=unknown, to be determined
Probability of accounting majors=30%=30/100=0.3
Sample size=3 business majors
Substituting;
Number of accounting majors=0.3×3=0.9
<em>Step 2: Determine the chance that at least one student majors in accounting</em>
The probability that at least one student majors in accounting=0.3×0.3×0.3=0.027
