Question 6: Isla has a box of counters. The table shows information about the shape and colours of the counters.
Shape
Aircle Triangle Square
Blues 6 2
Red
8 9 11
Colour
Isla picks a counter at random, looked at it and then returned it to the box.
(a) Given it is a circular counter, what is the probability that it was red?
David picks a counter at random, looked at it and then returned it to the box
(b) Given it is a blue counter, what is the probability that it was triangular?
Emily adds a number of red square counters to the box.
The probability of Emily picking a red square at random is now
2/3
(c) How many red square counters did Emily add to the box?

the largest number of the four options is 1.8 x 10-2

you have it in scientific notation.

1.80 x 10-6   = 0.00000180

1.80 x 10-4   = 0.000180 (bigger, or "less small", than the former one)

so

1.8 x 10-2       = 0.0180. as you see. the "less small", or the biggest one of them all.

as you have negative exponent, it means you are dividing 1.8 by 100 (i.e. moving the dot towards left, two times).

if you had positive exponent for the scientific notation, power of tenths, you would be multiplying times 100 (moving the dot towards right) as below:

1.8 x (10)2 = 180

so. if you have negative exponent in scientific notation, move the dot toward left. if it is positive, toward right as many times the exponent tells you.
