7C3=35 ways mother can go to cinema with distinct groups of three children
6C2=15 times a individual child will go to cinema before the group is repeated
this can also achieved by considering 1,2,3,4,5,6,7 as children
then writing the possibilities of 3 children
{123,124,125,126,127,134,135,136,137,145,146,156,157,167,234,235,236,237,345,346,347,456,457,567,245,246,247,256,257,267,356,357,367,467}
so total 35 and each number is repeating 15 times
