Step-by-step explanation:
The total number of coin in the first bag is given below as
The probabaility of picking an orange ball from the first ba will b calcuated below as
Step 2:
The total number of coin in the second bag is given below as
The probabaility of picking an orange ball from the second bag will be calcuated below as
Hence,
The probabaility of picking an orange coin from both bags will be calculated below as
Hence,
The final answer is
