Answer:
6.37%
Step-by-step explanation:
A deck of cards have 52 cards. There are 4 suits of 13 card each, those suits are Hearts, Clubs, Diamond and Spades.
The probability that the first card is a heart is:
![P(Hearts) = \frac{13}{52}](https://tex.z-dn.net/?f=P%28Hearts%29%20%3D%20%5Cfrac%7B13%7D%7B52%7D)
Now, the probabily that the second card is a diamond is:
![P(Diamond | First card is Heart) = \frac{13}{51}](https://tex.z-dn.net/?f=%20P%28Diamond%20%7C%20First%20card%20is%20Heart%29%20%3D%20%5Cfrac%7B13%7D%7B51%7D)
The Probability that the first card is a heart and the second one a diamond is given by:
×![P(Diamond | First card is Heart)](https://tex.z-dn.net/?f=P%28Diamond%20%7C%20First%20card%20is%20Heart%29)
![= \frac{13}{52}\frac{13}{51}](https://tex.z-dn.net/?f=%3D%20%5Cfrac%7B13%7D%7B52%7D%5Cfrac%7B13%7D%7B51%7D)

theres no photo
Step-by-step explanation:
Hello!
You first find out how many objects there are in total
4 + 9 + 3 = 16
Then you find the probability of Liliana picking a orange
Since there are 4 oranges and 16 things to pick she has a 4/16 chance of getting an orange
Next you find the probability of Liliana picking a pear
There are 3 pears and 16 items to pick so she has a 3/16 chance
Then you add them together to find the chance of either happening
4/16 + 3/16 = 7/16
So she has a 7 out of 16 chance of getting an orange or a pear
The answer is 7/16
Hope this helps!
Answer:
x=-4
Step-by-step explanation:
(x+4) ^ (1/3) + (2x+8) ^ (1/3) = 0
Subtract (x+4) ^ (1/3) from each side
(x+4) ^ (1/3) - (x+4) ^ (1/3)+ (2x+8) ^ (1/3) = -(x+4) ^ (1/3)
(2x+8) ^ (1/3) = -(x+4) ^ (1/3)
Cube each side
(2x+8) ^ (1/3) ^3= -(x+4) ^ (1/3)^3
2x+8 = -(x+4)
Distribute the negative sign
2x+8 = -x -4
Add x to each side
2x+8 +x =-x+x-4
3x+8 = -4
Subtract 8 from each side
3x+8-8 =-4-8
3x =-12
Divide by 3
3x/3 = -12/3
x = -4
