(iii) less than 65%marks in a unit test.

Answer-

Probability – the chances of something happening.

(iii)

The total number of times that the students who get less than 65% marks in a unit test = 0

Then,

P(less than 65% marks in a unit test)

= (Number of times student gets less than 65%marks in a unit test)/(total

number of tests taken by a student)

= \frac{0}{6}

= 0

Dividing Any number by zero, the only answer we get is zero
