From a pack of 9 cards numbered 1-9, three cards are drawn at random and laid on a table from left to right.
1 answer:
Answer: 1/6
Explanation: Since we need to draw three cards from a pack of 9 and the digits require an order, then our sample space becomes: 9P3.
Now, we don't care about picking an order when picking three cards to analyse, as there is only 1 way in arranging the three cards in descending order.
Thus, we get:
