Given : 

Cans of soda = 8

Cans of colas = 2

Cans of orange = 5

Cans of cherry = 1

Total = 8 + 2 + 5 + 1

= 16

So, probability = Favorable outcome/Total outcome 

Probability of 1st can being orange = 5/16

If 1st is not orange then, probability of 2nd being orange = 5/15

= 1/ 3

Probability of atleast 1 orange can = 5/16 + 1/ 3

= (15 + 16)/48

= 31/ 48

 

Hence, probability of at least one can being orange is 31/ 48.
