When starting a business, more women choose service industries that tend to have lower average sales levels. Those industries that do not directly produce tangible things are known as service industries (such as agriculture and manufacturing). The supply chain is the process through which items generated in the agricultural and manufacturing sectors are delivered to final customers.
Some service industries involved in this process include transportation, wholesale trade, and retail trade. Others are offered straight to customers. These include public administration, health care, education, information services, legal services, and financial services. Everything else falls under the category of service industries, which also includes banking, communications.

Answer:
(a) E(X) = 3
(b) Var(X) = 12.1067
Explanation:
(a) E[X]
E[X]T = E[X]T=A + E[X]T=B + E[X]T=C
= (2.6 + 3 + 3.4)/3
= 2.6 (1/3) + 3(1/3) + 3.4(1/3)
= 2.6/3 + 1 + 3.4/3
= 3
(b) Var (X) = E[X²]−(E[X])²
Recall that if Y ∼ Pois(λ), then E[Y 2] = λ+λ2. This implies that
E[X²] = [(2.6 + 2.6²) + (3 + 3²) + (3.4 + 3.4²)]/3
= (9.36 + 12 + 14.96)/3
= 36.32/3
= 12.1067
Var(X) = E[X²]−(E[X])²
= 12 - 3²
= 12.1067 - 9
= 3.1067
