Answer

Explanation:

Step1: Recall probability formula

The probability formula is $P(X) =\frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}}$.

Step2: Identify values

The number of groups that took a selfie 5 times (favorable outcomes) is 12. The total number of groups (total number of outcomes) is $27 + 29+18 + 14+12=100$.

Step3: Calculate probability

$P(5)=\frac{12}{100}= 0.12$

Answer:

$0.12$
