There are many black and white cats in the cage. Open the door of the cage to a small opening, let the cats jump out one by one, and record the colors of the cats that jumped out in turn, until 5 cats jumped out. Question: What is the probability that the 5 cats that jumped out are all black cats (note: expressed in fractions).
笼中关有许多黑猫和白猫，将笼门打开一个小小的口子，让猫一只接一只地往外跳，并依次记下所跳出的猫的颜色，直到跳出5只猫为止．问：跳出的5只猫恰好都是黑猫的可能性有多少(注：用分数表示)．
