Estimate 58% of 121 by using 10%

Basile [38]

58% is about equal to 60%, or 6 times 10%. 10% of 121 is 12.1.
12.1 * 6 = 72.6
To take this further, 58% is 2% less than 60%, or 2 times 1%. 1% of 121 is 1.21.
72.6 - (1.21 * 2) = 72.6 - 2.42 = 70.18

In three tries, the probability that she will get it right is:

$P=\frac{3}{4*4}\\P=\frac{3}{16}=0.1875$
