Students record the volume of a liquid by using three different measuring instruments X, Y and Z. The actual value of the liquid’s volume is $V$. The students’ outcomes are shown. How many of the instruments are precise and how many are accurate?
- Anumber of precise pieces of equipment: $1$, number of accurate pieces of equipment: $1$
- Bnumber of precise pieces of equipment: $1$, number of accurate pieces of equipment: $2$
- Cnumber of precise pieces of equipment: $2$, number of accurate pieces of equipment: $1$
- Dnumber of precise pieces of equipment: $2$, number of accurate pieces of equipment: $2$
