Answer 1

322 /738 ; 0.436

Explanation:

__________________ M____ F__

Eat oysters ________ 205 __ 113

Does not eat oysters _ 98 __ 322

Probability of choosing a female and does not eat oysters :

Number of (F n Does not eat oyster) = 322 (from table)

Total number of sample : (205+98+113+322) = 738

Hence,

Probability of choosing a female and does not eat oysters ;

Number of (F n Does not eat oyster) = 322 (from table) / total number of samples

= 322 / 738

= 0.436
