Question

3 white chips 7 blue chips 16 green chips 2 chips drawn from the box in succession what is the probability that one is blue and other is white

Answer 1

probability of getting a blue chip is
7/26
probability of getting a white chip is
2/26 = 1/13

Answer 2

Answer:  The required probability is 3.23%.

Step-by-step explanation:  Given that there are 3 white chips, 7 blue chips and 16 green chips in a box. Two chips are drawn from the box in succession.

We are to find the probability that one is blue and other is white.

We have

total number of chips in the box = 3 + 7 + 16 = 26.

Since the two chips are drawn in succession, so there will be no replacement of the first chip drawn.

Therefore, the probability that one chip is blue and other is white is given by

$p=\dfrac{7}{26}\times\dfrac{3}{25}=\dfrac{21}{650}\times100\%=3.23\%.$

Thus, the required probability is 3.23%.
