Parity is a bit checker so if Even no.of error occur it won't ditinguish.
EX: Data to b transmitted= 1010101
Even parity of 1010101 is '0' (if odd parity '1')
Let the data transmitted as
1. 1000101 - single bit error; parity is '1'
2. 1001101 - two bits error; parity is '0'
Therefore in 1 (ie single bit error) parity is missmatch
[Parity is calculated by just adding no.of ones; if we follow even parity then over count shd be 0, if not we shd set ie make parity as 1]

Parity checker is only used to detect one-bit errors.
