Svetllana [295]

Answer: 7/18

Step-by-step explanation:

Number of customers at Eva's boutique = 90

= Number of customers who wore a size extra-large / Number of customers at Eva's boutique

= 35 / 90

= 7/18

Therefore, the probability that a randomly selected customer wore a size extra large is 7/18.
