Answer

Answer:

$\frac{26}{40}=\frac{13}{20}$

Explanation:

Step1: Find total number of sunglasses

$2 + 12+4 + 11+4 + 7=40$

Step2: Find number of sunglasses with aviator or browline frames

$(4 + 7)+(4 + 11)=26$

Step3: Calculate probability

Probability = $\frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}}=\frac{26}{40}=\frac{13}{20}$
