Unfortunately, the English grammar is so bad, I'm not sure what it means!

Attempting to clarify it, I might change

Find the number of selection of 3 cards from the 6 cards if the digit is less than 6 and of even number.​

to

Find the number of selections of 3 cards from the 6 cards if the first digit is less than 6 and the number formed by the cards is even.​

or

Find the number of selections of 3 cards from the 6 cards if the first digit is less than 6 and is even.​

or

Find the number of selections of 3 cards from the 6 cards if each digit is less than 6 and is even.​

or other possibilities. None that I thought of give the right result.
