Probability

[JeanBidu]

I'm in doubt about this question if someone can help me how to assemble it I appreciate it

Suppose we have two urns. Urn I contains two black balls and three
while urn II contains three black and three white balls. we choose
a random urn and from it we extract a ball that has a white color. What is the
likely to be from the I urn? And the probability of being from urn II?

Suppose we have two urns. Urn I contains two black balls and three [white balls]
while urn II contains three black and three white balls. we choose
a random urn and from it we extract a ball that has a white color. What is the
[probability] to be from the I urn? And the probability of being from urn II?

I've corrected the problem; check that I am right.

Do you know Bayes' Theorem? That can be helpful, or you can just directly use the concept of conditional probability.

Find the probability that a ball is white and from urn I, and the probability that a ball is white and from urn II. Then use those to find the probability that a ball is from urn I, given that it is white.

Please show us whatever you can do, so we have some idea where you need help.
