Answer:

1/10

Step-by-step explanation:

P( 1st out of ink) = out of ink/total

                           =2/5

Then we have 4 pens left, 1 out of ink

P( 2nd pen out of ink) = out of ink/total

                           =1/4

P(2 pens out of ink) =P( 1st out of ink) * P( 2nd pen out of ink)

                                  = 2/5* 1/4

                                   =1/10
