So, the measure of angles 1 is

$11\cdot 6=66$

A SINGLE CARD IS DRAWN AT RANDOM FROM A STANDARD DECK OF 52 CARDS. FIND THE PROBABILITY OF DRAWING THE FOLLOWING CARDS. PLEASE R

erma4kov [3.2K]

Answer:

A. $\frac{17}{52}$

B. $\frac{17}{52}$

C. $\frac{2}{13}$

Step-by-step explanation:

There are 52/4 diamonds in the deck and 4 '5's in the dech of cards

52/4 = 13 + 4 = 17

Therefore, you have a $\frac{17}{52}$ chance of drawing one of those cards.

There are 13 hearts in the deck and 4 jacks. Therefore, your odds are the same : $\frac{17}{52}$

There are 4 jacks in a deck of cards and 4 '8's in a deck of cards

Therefore your probability is $\frac{8}{52}$ which simplifies to $=\frac{2}{13}$
