The formula for determining probability is expressed as
Probability = number of favorable outcomes/total number of possible outcomes
Since we are considering right paw,
number of favorable outcome = 12
Total number of possible outcomes = 38 + 12 = 50
Probability = 12/50 = 0.24
Expressing it in terms of percentage, it becomes
0.24 * 100 = 24%
Option A is correct
