Jocelynn Villa · Answer 1

The pen has a 50% probability. The crayon has 4.28 probability.

Anabella Preston · Answer 2

5:5 (first box, pencils to pens)

7:3 (second box, coloured pencils to crayons)

The probability of picking a pen (1st box) : 5/10

The probability of picking a crayon (2nd box) : 3/10

Probability of picking both: 5/10*3/10 = 15/100
