If A(r, s, t) be a function of the coordinates in n-dimensional space such that for an arbitrary vector B' of the type indicated by the index a A(r. s, t)B' is equal to the component C" of a contravariant tensor of order two. Prove that A(r, s, t) are the components of a tensor of the form A.

1. if we have 3 babies what is the probability they’re going to be all boys? 2. if we roll 2 die at the same time what is the probability of getting less than 10 on the first roll and a 5 on the second roll 3. if we have 3 babies what is the probability their is going to be 2 girls? 4. if we have 3 babies what is the probability of having no more than 1 girl? 5. it we have 3 babies and then have another 3 babies what is the probability of us having at least 1 boy and then having all girls?
