(a) No. The probability of drawing a specific second card depends on the identity of the first card.
Two events are independent if knowledge on the first doesn't change anything about the probability distribution of the second event. This isn't the case: since you don't replace the first card, you have some extra knowledge about the second.
If, for example, you pick the 7 of hearts at the beginning, you are sure that the second card won't be the 7 of hearts. This extra piece of information depends on the first pick, and so the two pick are not independent: knowledge about the first pick changed what you expect from the second pick.
(b)
The probability of finding ace on 1st card is 4/52 = 1/13, because there are four aces (one for each suit) out of 52 cards. If this happens, you're left with 51 cards, 4 of which are kings (one for each suit). So, the probability of picking a king among the remaining cards is 4/51. The probability of the two happening one after the other is
(c)
You can use the same logic as point (b)
(d)
We have 8 "good" cards for the first pick: any of the 4 aces or any of the 4 kings. So, the first pick has a success rate of 8/52 = 2/13. For the second pick we have 4 "good cards" (the 4 aces if we picked a king, the 4 kings if we picked an aces) out of the 51 remaining cards, so we have a success rate of 4/51. So, the probability of picking an ace and a king, in any order, is
One solution. Hope this helps!
Answer:
Perimeter = 64m
Step-by-step explanation:
I can only help for Perimeter.
12+20+12+8+8+4=64m
<span>The answer is 2 people. Jim and Holly are 2 persons making 2 gingerbreads for 2 minutes. So, for both of them, 2 minutes are necessary for 2 gingerbreads. Let's calculate how many gingerbreads they can make for 400 minutes. 2 min : 2 gingerbreads = 400 min : x gingerbreads. x = 2 gingerbreads * 400 min : 2 min = 400 gingerbreads. So, the two of them can make 400 gingerbreads for 400 minute without anyone's help.</span>
Answer:
ok in this case will represent the height with a the bells with b and the hypotenuse with c so it will be c squared is equals to a squared plus b squared 12 squared + 5 squared is equals to c squared 12 square is 144 while 5 squared is 25 when added it is 169 so csquared is equals to 169 to get c we find √ 169 source is equals to 13
