using this table of empirical probabilities, answer A and B

A. P($300 lessthan purchase lessthan $1000=

B. odds in favor of a purchase of $1000 or more is

a.) A=.37, B=7:93 b.) A=.37, B=93:7 c.) A=.78, B=7:93 d.)A=.78, B= 93:7

Solution

A:

P($300 < purchase <$1000)= 0.22+0.15=0.37

B:

Odds in favor of purchase of $1000 or more is

odds = (number of ways events can occur) : (number of ways events cannot occur)=0.07: (0.21+0.35+0.22+0.15)= 7 : 93

Hence, option (a) is correct.
