The probability of landing on the shaded region of the figure is 0.10
<h3>How to find the probability of landing on the shaded region?</h3>
The probability of landing on the shaded region can be calculated as follows;
area of the bigger circle = πr² = 3.14 × 25² = 1962.5 cm²
area of the smaller region = πr² = 3.14 × 8² = 200.96 cm²
Therefore,
the probability of landing on the shaded region of the figure = 200.96 / 1962.5
the probability of landing on the shaded region of the figure = 0.10

We can use #11 as an ex.
7ab and 4 ab
So we combine 7 and 4 (multiply)
=28
Then combine "a". On both sides they are 2 a"s so it would be a^2 and same for b . b^2
Answer: 28a^2b^2.
