Answer:
Step-by-step explanation:
We know that:
In a deck of 52 cards there are 4 aces.
Therefore the probability of obtaining an ace is:
P (x) = 4/52
The probability of not getting an ace is:
P ('x) = 1-4 / 52
P ('x) = 48/52
In this problem the number of aces obtained when extracting cards from the deck is a discrete random variable.
For a discrete random variable V, the expected value is defined as:
Where V is the value that the random variable can take and P (V) is the probability that it takes that value.
We have the following equation for the expected value:
In this problem the variable V can take the value V = 9 if an ace of the deck is obtained, with probability of 4/52, and can take the value V = -1 if an ace of the deck is not obtained, with a probability of 48 / 52
Therefore, expected value for V, the number of points obtained in the game is:
So:
Answer:
190 Baseballs
Step-by-step explanation:
Since he put 304 baseballs into 8 trash cans with an equal amt. in each,
--> we do 304/8 to find how much baseballs we put in each
=> 304/8 = 38
Now, we takes 5 of these 38 trash cans filled with balls to the field
--> we would do <em>5 x 38 => 5 x 38 = 190</em>
and Thus, we have our answer of <u>190 baseballs</u>
Hope this helps!
Answer:
#1: 10 bags
#2: 5 1/2 pounds
#3: 5 bags
Step-by-step explanation:
for number one you just count all the x
for number two I added all the pounds of the bags
for number 3 (im not sure if my answer was right for this one) theres only 5 x's on 1/2. so I think the answer is 5.
A) profit is 8$, the price increases 8$ every time or each pie is $4
B)N times 4= P
C) 15 times 4= $60 Profit. Because each pie is 4$
D) if 144$ are made and each pie is $4, you’d divide 144 by 4= 36. 36 Pies were sold.
I hope this is correct and helps :)
