There are 13 hearts in the deck of 52.
If we want to simply choose 7 of them, we use combinatorics, and not permutations.
Thus, the total number of ways to choose 7 of the 13 hearts, is: ¹³C₇ or 1716 ways.
The total in our sample space is simply choosing 7 of the 52 cards, which is: ⁵²C₇ or 133 784 560.
Thus, the probability becomes:
20/12 = 1.6 recurring (that is, 1.6666...)
X=500 I mean division is the answer to x=500
Distance biked before lunch = 1
km (the number is written in mixed fraction)
⇒ Distance biked before lunch = 
Distance biked after lunch = 6
km (the number is written in mixed fraction)
⇒ Distance biked after lunch = 
We need to determine how much farther does Hallie bike after lunch than before lunch
Extra distance biked after lunch vs. before lunch =
- 
⇒ Extra distance biked after lunch vs. before lunch = 
⇒ Extra distance biked after lunch vs. before lunch = 
⇒ Extra distance biked after lunch vs. before lunch = 4
(in mixed fraction)
Hence, Hallie biked 4
km extra after lunch vs. before lunch.
