Question

Find the probability of getting a numbered card when a card is drawn from the pack of 52 cards.

Answer 1

`(9)/(13)`

Explanation:

1. the formula is: p=(number_of_numbered_cards)/(total_number_of_cards);

2. the number of total numbers of the cards is 52 (according to the condition); the number of the numbered cards is:

4*(10-2+1)=36 (min is '2'; max is '10').

3. after the substitution:

p=36/52=9/13≈0.692
