$20 C \cdot 2 {(0.1)}^{2} {(0.9)}^{20 - 2}$

Step 1

Raise $0.1$ to the power of $2$ .

$20 C \cdot (2 \cdot 0.01 {(0.9)}^{20 - 2})$

Step 2

Multiply $2$ by $0.01$ .

$20 C \cdot (0.02 {(0.9)}^{20 - 2})$

Step 3

Subtract $2$ from $20$ .

$20 C \cdot (0.02 \cdot {0.9}^{18})$

Step 4

Raise $0.9$ to the power of $18$ .

$20 C \cdot (0.02 \cdot 0.15009463)$

Step 5

Multiply $0.02$ by $0.15009463$ .

$20 C \cdot 0.00300189$

Step 6

Multiply $0.00300189$ by $20$ .
