Answer 10

A probability that it will lend on a specific number (lets say, only on number "3") is 1/8.
Because it can lend on 1 fielf out of 8.

Now, for it to lend on any number 1-7 (including 1 and 7) is 7/8
because it can lend on 7 possible fields out of all 8.

When you want it to lend on an even number:
1) how many fields with even numbers there are?
2) How many possibilities is it out of 8?
3) What is (therefore) your answer ?
