150

Answer 2

Answer: 149

Step-by-step explanation:

• Given, No. of white ball= 5
• No. of green ball= 4
• No. of blue ball= 4
• To find the number of ways in which one or more balls will be selected= [(1+5)(1+4)(1+4)]-1

                      = [6*5*5]-1

                      = 150-1

                      = 149

• Hence, the required number of ways in which one or more ball will be selected is 149.
