### Food-for-Thought: What's the Probably of finding the missing plane?

The following is reported in online Straits Times today (16 March).
Click HERE to read the report and to access the dynamic graphic to have a visual sense on the size.

With the possibility that the MH370 is hijacked, based on the amount of fuel that the missing plane carried with it, the airports that the plane could possibility had landed are identified (in the map shown). According to WNYC, the missing plane could have landed in 634 runways in 26 different countries.

Now, are you able to tell the likelihood, that is, the chances that you will find the plane if you just pick any of these airports? Mathematically, it's possible to have equal chances of finding it in any airport, based on ideal situation. However, the chances of finding the planes in all airport vary now. Why?

### Food-for-Thought: Searching for a needle in a haystack

The following is reported in online Straits Times today (15 March).
Click HERE to read the report and to access the dynamic graphic to have a visual sense on the size.

MH370 has gone missing for more than 7 days and the relevant authorities have expanded the search area to locating the missing plane. Below is the visual representation to give us a sense of how difficult it is to location an object in a vast area.

Based on the information given in the article, and the 'suggested' size of the search area, are you able to estimate the chance of locating MH370 at the 'defined' search area?

### Consultation during March Holidays

During the holidays, you may go through the following channels if you need to clarify areas that you are not sure (as you do your homework/ revision):

• Email
• Remember to include the question in the email.
• Attempt the question first before you say "do not know how to do". Then take a photo of the working and write down which part you are not sure. Email the photo to me.
• If you do not understand the question, or do not know how to start solving the problem, include the question (either type it or take a photo) and tell me which part of the question you are not sure.
• Note: When sending email, remember to address the email to me; and sign off with your name and class.
• Face-to-Face session
• I'll be in school from Monday to Thursday; however, will be conducting support programme or running other programmes or attending workshop.
• Therefore, you should make an appointment (at least a day before, via email) with me to ensure that I have time set aside to meet and discuss the work with you.

### Revision: Enquiry on Chap 2 - Real Numbers

A question from Joshua Yew:

Is 0 a rational number?

A number is a rational number if we can expressed it as a fraction a/b where a and b are integers and b is not zero.

Let's look at zero - it is a result from fractions like 0/5, 0/89 ?

In other words, Zero can be expressed a fraction such that the numerator is an integer and the denominator is an integer that is not zero.
Hence 0 is a rational number.
