1. (a) A sequence of integers (a1, a2,..., an) is weakly increasing if a₁ ≤ a2 ≤ ≤ an. For instance, (0, 2, 2, 3, 5) is weakly increasing, but (0, 2, 2, 1, 5) is not. Determine the number of weakly increasing sequences of length 10 where 0 ≤ a, ≤ 5 for every 1 ≤ i ≤ 10. (b) Determine the number of ten digit phone numbers containing at least one of each odd digit.

1. (a) A sequence of integers (a1, a2,..., an) is weakly increasing if a ≤ a2 ≤.. ≤ an. For instance, (0, 2, 2, 3, 5) is weakly increasing, but (0, 2, 2, 1, 5) is not. Determine the number of weakly increasing sequences of length 10 where 0 ≤ ai ≤ 5 for every 1 ≤ i ≤ 10. (b) Determine the number of ten digit phone numbers containing at least one of each odd digit.
