Here n = 100
Required probability = the probability that exactly 26 of them will have this allergy
=
The equivalent expression is
. Option B
<h3>How to determine the expression</h3>
Given the expression
= 
Divide the multipliers, we have
= 
Let factorize the numerator in square root
= 
Eliminate the like factor in both the numerator and denominator
= 
Let's bring forth the 'x' factor, we have
= 
Thus, the equivalent expression
