Answer:

Step-by-step explanation:
Given
Balls = 1 to 4
Required
Determine the probability of selecting ball numbered at least 2
Here, we'll assume that all numbers have the same probability.
The probability of each ball will be:

So:

Recall that
--- for each ball
So, the equation becomes



Answer:
44, 6, and 24 are not perfect square
Step-by-step explanation:
Perfect square are numbers that can be square rooted with a result of a perfect whole number.
√16=4
√44= 6.63324...
√81= 9
√6= 2.44948...
√49= 7
√24= 4.898997...
