Suppose the market portfolio is equally likely to increase by $12\%$ or decrease by $3\%.$

a$.$ Calculate the beta of a firm that goes up on average by $15\%$ when the market goes up and goes down by $4\%$ when the market goes down.

b$.$ Calculate the beta of a firm that goes up on average by $19\%$ when the market goes down and goes down by $9\%$ when the market goes up$.$

c$.$ Calculate the beta of a firm that is expected to go up $4\%$ independently of the market.

a$.$ Calculate the beta of a firm that goes up on average by $15\%$ when the market goes up and goes down by $4\%$ when the market goes down.

The beta is

$($Round to two decimal places.$)$
