Independent Pursuits: Puzzle

I HAVE in my pocket two coins. One is normal, with a head on one side and a tail on the other. The other coin is double-headed. I take one of the coins out of my pocket at random, look at one side of it, and see a head. What is the probability that the coin I have selected has a head on the other side too?

And while you are thinking about this, where might an adornment and protection come into it? (Answers on Monday).

Yesterday's answer:

The odd pair out was LARGE - FIREPLACE. In all the others, the two words are linked by a third word that can mean either of them:

EQUAL (match) CONTEST

BEAK (bill) INVOICE

EXERCISE (train) LOCOMOTIVE

RUBBISH (junk) BOAT.

The LARGE - FIREPLACE pair are linked by two words sounding the same but spelt differently: great and grate.
