Answer

Answer:

$0.29$

Explanation:

Step1: Recall probability formula

$P(X) = \frac{\text{Frequency of }X}{\text{Total frequency}}$

Step2: Identify relevant values

Total frequency = $27 + 29+18 + 14+12=100$. Frequency of taking selfie 2 times = $29$.

Step3: Calculate probability

$P(2)=\frac{29}{100}=0.29$
