Maths Week: Your Saturday puzzle

Figure it out.

IT’S MATHS WEEK, and as is our annual tradition here, we’re setting you a puzzle a day with all answers published on the site on Sunday.

Get puzzling!

TODAY’S Q: 

Your friend who is an inveterate gambler drops two Irish euro coins on the table, covers them and says, “We’ll have a little bet on Eurozone map or harps. I’ll be Eurozone maps and you’ll be harps”.

You can’t see which way the coins are facing but you suggest the following rules. If both coins are showing harps they are to be shaken and tossed again. If the coins are not both harps, your friend will slide out a coin showing the Eurozone side. You will bet €5 that the other coin is showing harps up. Your friend thinks that this is quite generous of you. Is it?

All answers will be published on TheJournal.ie on Sunday
