Respuesta :

apologiabiology
that is desired outcomes/total possible outcomes

desired=7 blue
total=total number of marbles=11+7+9+13=40

7/40 is da answer
first calculate the total amount of marbles 11 + 7 + 9 + 13 = 40

there are 7 blue marbles and a total of 40 marbles so theoretical probability of picking a blue marble from the bag is 7/40. hope this helps.
