Answer:

second marble is blue and first marble is white is $\frac{1}{7}$

Step-by-step explanation:

given data

two marbles

box = 1 blue, 3 white, 2 green, and 2 red marbles

solution

we get here second marble is blue and given that the first marble is white

= P(3c1 × 1c1) ÷ P(3c1 × 7c1) ................................................1

= 1c1 ÷ 7c1

= 1 ÷ 7

so second marble is blue and first marble is white is $\frac{1}{7}$
