I hate online school brub
His answers are wrong plz listen to me
I really need help with this test.
The total number of possible outcomes is the product of the number of options for each accessory:
Total possible outcomes = 3 necklaces * 2 bracelets * 3 hats = 18
The desired outcome is Sammy choosing a red necklace and a yellow bracelet. According to the table, the probability of each of these individual events occurring is:
Probability of choosing a red necklace = 1/4
Probability of choosing a yellow bracelet = 1/2
The probability of both of these events happening together is the product of the individual probabilities:
Probability of choosing a red necklace and yellow bracelet = (1/4) * (1/2) = 1/8
So, the probability of Sammy choosing a red necklace and a yellow bracelet is 1/8 or 0.125.
you have 2, 5, 6 right
It would help if you numbered your questions.
1. your last choice is dependent , thus NOT independent
D
2. prob(heads and 3) = (1/2)(1/6) = 1/12
D
3. prob = 1/4, so of 36 cases, we can expect 9
C
4. prob(4door) = .56, so of 300 asked we expect 168
B
5. Prob(defective) = 7/50
number defective in 1000 = (7/50)(1000) = 140
A , YEAHH, you guessed one right!!
6. number of cones = (5)(9) = 45
B
These are very basic and elementary question in probability, I think you are just guessing
asalam salam
HE cORRECT!!!! i GOT 14/14 last qestios is an easy people like u just dont want u to get the awnsers
Is this the exploring probability unit test for connexus
Bot i need help
Of course, I would be happy to help. What are your questions?
Which event are not independent?
A. Landing on heads after tossing a coin and rolling a 3 on a 6 sided nuber cube.
B. Choosing a marble from a jar and landing on tails after tossing a coin.
C. Choosing a 5 from a deck of cards, replacing it, and then choosing an ace as the second card.
D. Choosing a card at random from a deck, without replacing it, and choosing another card at random.
Bot help me with that
The event that is not independent is option C: choosing a 5 from a deck of cards, replacing it, and then choosing an ace as the second card.
This is because the probability of choosing an ace as the second card is affected by the fact that a 5 was previously chosen and replaced in the deck.
Bot help me on. Sammy like to mix and match her necklace, 2 braclets, and 3 hats. The colors are listed in the table. On Monday, she randomly picks a bracelet, a necklace, and a hat. What is the possibility of Sammy choosing a red necklace and yellow bracelet? Necklace:Red, Green, Gold Silver. Bracelet: Red Yellow
Thank you very much bot

You're expecting someone to take your test for you??
If you post what YOU THINK (no guessing!) the answers are, someone here might check them for you.
