<span>The probability is given as No of favourable outcomes over total number of events. Now, the no of clubs in a deck of cards is 13 and similarly, the number of jacks in a deck of cards is 13. Then, the probability that a card picked at random from a 52-card deck of playing cards is a club or a jack = 13+13/52 = 26/52 = 1/2 = 50%</span>
Answer:
4.1
Step-by-step explanation:
<u><em>You can use the Pythagorean Theorem to solve this:</em></u>

<u><em>Plug in the numbers into the formula:</em></u>

16 + 1 = 
17 = 
<u><em>Square both sides:</em></u>

4.12 = c
4.1 = c
