65(7) = 455 sit-ups during a 7 day period
The probability of drawing a heart from the standard deck of cards and then drawing a 5 is 1/52
<h3>How to determine the probability?</h3>
In a standard deck of cards, we have:
Total = 52
Heart = 13
5's = 4
Since the cards are replaced, the probability is calculated as:
P(Heart and 5) = Heart/Total * 5s/Total
This gives
P(Heart and 5) = 13/52* 4/52
Evaluate
P(Heart and 5) = 1/52
Hence, the probability of drawing a heart from the standard deck of cards and then drawing a 5 is 1/52
