Answer

Answer:

$\frac{21}{46}$

Explanation:

Step1: Identify total number of students

The total number of students is 46.

Step2: Identify number of students with grade B

The number of students who got a B is 21.

Step3: Calculate probability

The probability $P$ of a student getting a B is $P=\frac{\text{Number of students with B}}{\text{Total number of students}}=\frac{21}{46}$.
