Question

a matchbox is dropped on the table.
experiments show that it lands:on its end with probability 0.1
on its edge with probability
and the rest of the time with its flat face.
what is the probability that the first box lands on its end and the second box land on its flat face

Answer 1

P(the first box lands on its end and the second box land on its flat face) =

= P(box lands on its end) * P (box lands on its flat face) =

& =& 0.1*(1-0.1-E),

where E is the probability that the box lands on its edge.
