Have a Heart!

ok – Let’s see who stands where here.

As posed by Bruce Aubertin:

Andy and Barb are a couple at a casino, gambling on getting two aces in a pair dealt face down from a (well-shuffled) standard deck of 52. At one dealing Andy happened to glimpse that one of the cards was a heart, and whispered to Barb, “Hey, let’s up our bet, because the probability of two aces given at least one heart in the pair is a bit higher now (the house is playing this one as a fair game, and Andy thinks if they bet big when they get a glimpse like this then they can beat the house in the long run). Barb replied, “Don’t be stupid Andy, our chances are exactly the same, I mean what if you saw a club or some other suit, you only saw the suit, it’s not as if you saw one of the cards was an ace!”

Who is right in this?
(Barb is supporting Andy, a bit of a math geek, through school.)

The above was prompted by a discussion near the end of the ‘Playground’ problems section of the latest ‘Math Horizons’ magazine (see the section headed “Five more minutes, kids!”).

Blog Action Day

This year’s Blog Action Day is devoted to the theme of Climate Change and an understanding of mathematics is certainly essential for anyone involved in making making decisions about how to respond to this issue (which in a democracy is presumably all of us).

Connections in Mathematics

Since the theme of this year’s Welcome to Langara Day was “Get Connected”, it seems worthwhile to look at some of the ways in which this applies to Mathematics, and this post amplifies on the three themes identified in the departmental posting linked to above.
