Throw two dice and calculate the probability that the sum of points is less than 7.

When you roll the dice twice, one * * * appears in different situations: 6×6=36 kinds.

Where the sum of points is less than 7: 1 and 1, 1 and 2, 1 and 3, 1 and 4, 1 and 5; 2 and 1, 2 and 2, 2 and 3, 2 and 4; 3 and 1, 3 and 2, 3 and 3; 4 and 1, 4 and 2; 5 and 1

A * * * has: 5+4+3+2+ 1= 15 kinds.

So the probability of this event is: 15÷36=5/ 12.
