3. Un supermercado entrega boletos a todos sus clientes, para quienes realicen compras menores de 10 dólares un boleto de color naranja, compras entre $10 y $20 dólares un color amarillo, entre $20 y $30 dólares un color azul y para los que realicen compras mayores a $40 dólares un boleto color verde. Para escoger a los ganadores se hace girar la ruleta (como se muestra en la figura). Determine la probabilidad de que gane una persona que gastó $25 dólares en compras.

Incomplete question. However, additional information provided below

Step-by-step explanation:

Here is a clearer rendering of the requirements of the question below:

"A supermarket delivers tickets to all its customers, for those who make purchases under $ 10 an orange ticket, purchases between $ 10 and $ 20 a yellow color, between $ 20 and $ 30 a blue color and for those who make larger purchases at $ 40 dollars a green ticket. To choose the winners, spin the roulette (as shown in the figure). Determine the probability that a person who spent $ 25 on purchases will win."

Thus, you are required to focus your probability calculations on the $ 20 and $ 30 customers category who are given a blue color ticket, since a person who spends $25 is within this category.
