card?

Respuesta :

Answer:

9 / 14 for a brown , 3 / 14 for a blue

Step-by-step explanation:

1) summarize all cards 9 (brown) + 2 (yellow) + 3 (blue)= 14 cards.

2) probability depends on how many cards of a particular color, how more cards, then more probability.  

3) 9 brown cards, so probability = 9 brown cards to divide all cards 14.
