A bin contains 4 red balls and 9 blue balls. Several balls are drawn from the bin. Given that the 6th ball drawn is blue, what is the probability that the 7th ball drawn is red?

Respuesta :

Answer:

we assume that the balls are drawn with replacement since it not stated,now we know that ;

probability=required outcome/possible outcome.

we define possible outcome as the total number of events;in particular we say 4red balls + 9 blue balls=13 balls

now, red balls=4 and blue balls=9, since we want to find the probability of drawing a red ball we say;

probability=[tex]\frac{4}{13}=0.307[/tex]

Step-by-step explanation:

probability: this is the likelihood of an even happening or occurring.
