Dropped Dr Zonga

Answer

While this sounds quite challenging, the way to tackle it is to go letter-by-letter. Start by asking what it is the probability of the first letter you pick-up being a D. There are 7 letters in total, so you have a 1 in 7 chance of picking up the letter you want. Thus, the probability of choosing D = 1/7

Then, do the same for the second letter, R. Now there are only six letters left on the floor, so the probability of you picking up the R = 1/6. To recap, the probability of picking up the D and then the R is 1/7 x 1/6 = 1/42.

Continue to do this for each letter and you end up with

1/7 x 1/6 x 1/5 x 1/4 x 1/3 x 1/2 x 1/1 = 1/5040

So, the probability of you picking all letters up in the correct order is 1 in 5040 or 1/5040.

Moving again Answer

Which countries might they move to next?

Dr Zonga: Andorra, Belgium, Canada, Dominican Republic, ...?

For Dr Zonga, each country started with the next letter in the alphabet. Thus, the next country Dr Zonga might move to would start with an E. Correct answers we received included:

Ecuador (thanks Simon)

Egypt (nice work Julian)

Eritrea (good find Steve)

England (good old blighty - well done Isaiah and Allegra)

Dr Zonga's Friend: Argentina, Denmark, Iceland, Portugal, ...?

This one was slightly trickier to notice. If we assign numbers to the first letter of each country, based upon its position in the alphabet, they go as follows:

A = 1

D = 4

I = 9

P = 16

These are the square numbers of 1,2,3,4. Thus the next number will be the square of 5. Which is 25. And the letter associated to this number? Y

Many people worked this out, and they all came back with the same country - Yemen. I guess not many countries start with the letter Y...

Well done if you worked out either or both of these.

Football Triangles Answer

Question 1

Goal Area (width x height):

2.44m x 7.32m = 17.86 metres squared

Triangle Area (width x height / 2):

0.5m x 0.5m / 2 = 0.125 metres squared

Two triangles = 0.125 + 0.125 = 0.25 metres squared

% of Goal covered by Triangles = (Area of Triangles / Area of Goal) x 100

(0.25 / 17.86) x 100 = 1.4%

So only 1.4% of the goal is covered by the triangles. Great job if you worked this out, or if you managed to get the ball in the triangles!
