Solution:

Given:

The figure is:

(the first photo)

To find:

The probability of event A.

Step-by-step explanation:

Consider the given figure,

(the second photo)

We know that,


probability = (number \: of \: favourable \: outcomes)/(total \: number \: of \: outcomes)

The number of favorable outcomes = 18

The total number of outcomes = 18 + 12 + 6 = 36

Therefore,

The probability of event A is


P(A) = (18)/(36)


P(A) = 0.50

Final answer:

The probability of event A is 0.50.
