The number of significant figures in 0.000040027 m² is 5.

If the number is less than one, then the zeroes on the right of the decimal point (but left to the first non-zero) are insignificant. Hence, all four zeroes appearing before 4 are not significant figure. All zero between two non-zero digit are always significant. Hence, the remaining five digits are significant figures.

Example

Each numeral on a die is equally likely to occur when the die is tossed.

Sample space of throwing a die: { 1, 2, 3, 4, 5, 6 }

From this we can make conclusions such as the following:

Getting a 3 on the toss of a die and getting a 5 on the toss of a die are equally likely events, since the probabilities of each event are equal.
Getting an even number on the toss of a die and getting an odd number on the toss of a die are equally likely events, since the probabilities of each event are equal.
Getting a 1, 2 or 3 on the toss of a die and getting a 4, 5 or 6 on the toss of a die are equally likely events, since the probabilities of each event are equal.

The colour of ferrous sulphate is green. It changes to brown after heating.

On heating: FeSO₄.7H₂O→FeSO₄(s)+7H₂O(g)

The product formed is ferric oxide (Fe2O3). This is a decomposition reaction.

On strong heating: 2FeSO₄(s)→Fe₂O₃(s)+SO₂(g)+SO₃(g
