Replace the ball from the first draw. So after replacement, the box again contains 3 orange and 2 blue balls. Draw another ball that could again be either blue or orange. Method 2 (Without replacement): Draw a ball, and it could be blue or orange.

WebIn mathematics, permutation is a technique that determines the number of possible ways in which elements of a set can be arranged. For Example, the permutation of Set Z = { 1, 2 } is 2, i.e., { 1, 2 } and { 2, 1 }. We can see from this example that these are the only two possibilities in which the elements can be arranged.
