Well to solve these type of question it is very easy to make a tree diagram and then solve them. How ever i have done it here for you.
So basically we have to get a pen from the first box so its probability is 7 / 10.
Similarly, we have to get a crayon from the second box so its probability is 2 / 8.
Now by counting principle we can multiply the two probabilities so 7/10 * 1/4 which becomes equal to 7/40.
Put the whole number over 1,
2 x 3/4
2/1 x 3/4
Now you would multiply across
6/4

Answer:
7 units
Step-by-step explanation:
(-2,6)=(X1,Y1)
(-2, -1)=(X2,Y2)
now ,
distance=√{(x2-x1)^2+(y2-y1)^2}
=√{(-2+2)^2+(-1-6)^2}
=√49
=7 units
