Naema's Juice Shopping

Can select 1 jug of juice from the 3 juices. Number of ways to select 1 jug of juice from the 3 juices = 3C1 = 3

Can select 1 can of juice from the 4 juice cans. Number of ways to select 1 can of juice from the 4 juices = 4C1 = 4

Total ways = 4 + 3 = 7

THERE IS 7 TYPE OF DIFFERENT JUICES SO THERE IS 7 DIFFERENT CHOICES

1 jug can be selected in 3C1 ways and 1 Can can be selected in 4C1 ways =3C1+4C1 =3+4 =7

Naema has to choose any one out of the 7 choices, so she can choose in = 7C1 = 7 ways.

As the sum rule states , it will be only applicable then when you can't do two or more operation at a time. If we look into our problem , it states"Naema wants only one can or jug of juice". That means either she has to choose 1 can (where she has 4 option) or 1 jug(where she has 3 option). As she can't take both jug & can, according to sum rule the ans is: 4+3=7. :-D

Naema wants juice all kind of juice means frozen cans or Jug of Juice so calculate all the fruit and add them it is 7, So 7 is the right answer................

There are 4 choices for frozen can then 3 choices for jug of juice or meant add

hence 4+3=7
