There are 
chairs in the lecture hall, which are divided into 
rows so that each row has the same number of chairs. 
mathematics students randomly sit on the chairs: Mark, Evra, Ela, Jane, Tim, Nic, Luke and Franca.
Calculate the event probabilities:
A - the first row remains empty,
B - exactly 
chairs are occupied in the first row,
C - all students sat in the same row.
Mark, Evra, Ela, Jane, Tim, Nic, Luke and Franca play board games in the afternoons. Everyone rolls a fair dice exactly once.
Calculate the probabilities of the events:
D - no one rolls a six,
E - exactly two roll a six,
F - at least two roll a six and
H - only Maja and France throw a six.
