Answer:

0.4

Step-by-step explanation:

If the ratio of boys to girls in a class is 2:3, then

there are 3x girls.

If there are 18 girls in the class, then

$3x=18\\ \\x=6$

Thus, there are

$2\cdot 6=12$ boys;
$3\cdot 6=18$ girls;
$12+18=30$ students in total.

The probability of a boy being in the class is

$P=\dfrac{12}{30}=\dfrac{2}{5}=0.4$
