Global Computer, a computer manufacturer with a global supply chain, is adding a new supplier for some of its component parts, and the suppliers it$$s considering are in China, India, Thailand, and Vietnam. As a part of its risk management program, Global Computer wants to assess the possible impact of a supplier shutdown in the event of a natural disaster, such as a flood, fire, an earthquake. The following payoff table summarizes its profits $($in millions of dollars$)$ for supplier shutdowns given three different levels of event severity.

Supplier country Low severity Moderate severity High severity

China $$32$ $$18-$$$8$

India $$30$ $$15-$$$6$

Thailand $$28$ $$20-$$$3$

Vietnam $$26$ $$15-$$$5$

$1)$ Find the best option by

a$.$ Maximax payoff

b$.$ Maximin payoff

c$.$ Minimax regret

$2)$ For more thorough planning, they hired a consultant, and the consultant forecasted the probability of $$moderate severity$$ as $50\%,$ and the probability of $$high severity$$ as $30\%.$ Which location should be the best option?
