**** There are different ways to select two objects at a time. (Type a whole number.) Explain why this result is different from the result when order matters. Choose the correct answer below. OA. When order matters, picking the first object before the second object is the same as picking the second object before the first object. Therefore, the number of ways of choosing is greater than when order does not matter. OB. When order does not matter, picking the first object before the second object is the same as picking the second object before the first object. Therefore, the number of ways of choosing is greater than when order matters. OC. When order matters, picking the first object before the second object is not the same as picking the second object before the first object. Therefore, the number of ways of choosing is less than when order does not matter. OD. When order does not matter, picking the first object before the second object is the same as picking the second object before the first object. Therefore, the number of ways of choosing is less than when order matters.

result different from the result when order matters?
There are different ways to select two objects at a time.
(Type a whole number.)
Explain why this result is different from the result when order matters. Choose the correct answer below.
OA. When order matters, picking the first object before the second object is the same as picking the second
object before the first object. Therefore, the number of ways of choosing is greater than when order does not
matter.
OB. When order does not matter, picking the first object before the second object is the same as picking the
second object before the first object. Therefore, the number of ways of choosing is greater than when order
matters.
OC. When order matters, picking the first object before the second object is not the same as picking the second
object before the first object. Therefore, the number of ways of choosing is less than when order does not
matter.
OD. When order does not matter, picking the first object before the second object is the same as picking the
second object before the first object. Therefore, the number of ways of choosing is less than when order
matters.
