Um A has balls numbered 1 through 6. Urn B has balls numbered 1 through 3. What is the probability that a 4 is drawm from A followed by a 2 from B?
To find the probability that a 4 is drawn from A followed by a 2 from B, we first need to find the probability of drawing a 4 from A and then the probability of drawing a 2 from B.
The probability of drawing a 4 from A is 1 out of 6, since there is only one 4 out of the total of 6 balls in urn A.
The probability of drawing a 2 from B is 1 out of 3, since there is only one 2 out of the total of 3 balls in urn B.
To calculate the probability of both events occurring, we multiply the individual probabilities together:
(1/6) * (1/3) = 1/18
Therefore, the probability that a 4 is drawn from A followed by a 2 from B is 1/18.
