69 pounds

Step-by-step explanation:

5 x 42 = 210 - 20 = 190       Bobbi

3 x 42 = 126 - 5 = 121           Amira

190 - 121 = 69

Step-by-step explanation:

We are given that : For breakfast Bob has three options: cereal, eggs or fruit. He has to choose exactly two items out of the three available.

  Part a ) Describe the sample of this experiment.

Since we have to choose two items out of the three available. So number of possible outcomes could be:

  i) Cereal , Eggs

  ii) Cereal , Fruit

  iii) Eggs , Fruit

Thus sample space is S = { (Cereal , Eggs) , ( Cereal , Fruit ) , ( Eggs , Fruit ) }

Part b)   A : Bob's breakfast includes cereal , we have to express this event as a subset of sample space.

Thus two outcomes includes Cereal = (Cereal , Eggs) , ( Cereal , Fruit )

Thus A = { (Cereal , Eggs) , ( Cereal , Fruit ) }
