Step-by-step explanation:

total - no nuts = nuts    186 - 104 = 82

total - o raisin = chip = 82 - 40 =42

2/3 of the cookies are c chip 2/3 * 186 = 124

124- 42 = 82  no nuts

104 - 82 = 22

40 +22 = 62

                   c chip               o raisin               total

nuts              42                      40                        82

no nuts          82                    22                          104

total             124                     62                           186

P ( nuts) =  number of nuts / total  in the   total column 82 / 186 =41/93

P (nuts | oatmeal)  =  nuts / total in the oatmeal column =40/ 62 =20/31

They are not independent

They need to have the same probability to be independent

A) 41 / 93

2) 20 / 93

3) No

Step-by-step explanation:

With nuts total = 186-104 = 82

Chocolate chips with nuts = 82-40 = 42

2/3 of cookies are chocolate chip.

So,

2/3 * Total

=> 2/3 * 186

=> 2 * 62

=> 124 chocolate chip cookies

A) Probability of having nuts = With nut cookies / Total

=> 82 / 186

=> 41 / 93

B) Probability of Oatmeal raisin cookie having nuts = Oatmeal nut cookies / Total

=> 40 / 186

=> 20 / 93

C) They are not independent of each other. They are dependent on each other. If they were independent their probability were to be same.
