Suppose you deal 3 cards from a regular 52 card deck what is the probability that they will be all jacks?

the probability of your 3 cards to be all jack is 4 over 52.

WHy?

because in a card deck, there are a total of 52 cards and each value of of the cards has 4 copies each.

For the jack, we have 4 and here are the following

=> Jack of spades

=> jack of hearts

=> jack of diamond

=> and jack of clubs

Thus, the probability is 4 over 52.

1/5525? I think 4/52 for the first one, 3/51 for the second, and 2/50 for the last one. Multiply them all together and you have your answer
