Answer 1

Given,

The total number of student got C is 15.

The total number of students is 61.

Required

The probability of getting C.

The probability of getting C is,

`\begin{gathered} Probability=\frac{total\text{ number of students with C}}{total\text{ students}} \\ =(15)/(61) \\ =0.246 \end{gathered}`

Hence, the probability of student getting C is 0.246.
