Final answer:
The probability of not being dealt a card with a number from 2 to 5 is 9/13.
Step-by-step explanation:
To find the probability of not being dealt a card with a number from 2 to 5, we first need to determine the number of cards that satisfy this condition. There are four cards with a number 2, four cards with a number 3, four cards with a number 4, and four cards with a number 5. Therefore, there are a total of 16 cards (4+4+4+4) that we don't want to be dealt.
The total number of cards in a deck is 52. So the probability of not being dealt a card with a number from 2 to 5 is (52-16)/52, which simplifies to 36/52. This fraction can be simplified further to 9/13.
