the probability of getting a black one given that in the first draw we got a black one is P = 1/2 = 0.5

How to find the probability?

We will assume that all the beads have the same probability of being randomly selected.

Then the probability of picking a black bead is equal to the quotient between the number of black beads and the total number of beads.

Originally, there are 4 black ones and 3 red ones ( a total of 7).

We want to get the probability of getting a black one given that in the first draw we got a black one.

If in the first draw we got a black one, then now there are 3 blacks and 3 reds (a total of 6 beads).

So the probability of getting another black one is:

P = 3/6 = 1/2 = 0.5
