A bag contains 6 green marbles and 5 white Marbles. You select a marble at random. What are the odds in favor of picking a green marble?
1:6
5:6
6:5
6:11
I think its 6:11
You are right.
Since there is 11 total marbles the correct answer is 6/11.
Thank you :)

A bag contains 6 green marbles and 5 white marbles. You select a marble at random. What are the odds in favor of picking a green marble?
The experimental probability of winning a free gallon of milk can be found by dividing the number of customers who received a star on their receipt by the total number of customers:
Total number of customers = 264
Number of customers who did not receive a star on their receipt = 219
Number of customers who received a star on their receipt = 264 - 219 = 45
Experimental probability of winning a free gallon of milk = Number of customers who received a star / Total number of customers = 45/264
Simplifying this fraction by dividing both the numerator and denominator by 3, we get:
Experimental probability of winning a free gallon of milk = 15/88
Therefore, the experimental probability of winning a free gallon of milk is 15/88.
The odds in favor of picking a green marble are 6:5.
Food Express is running a special promotion in which customers can win a free gallon of milk with their food purchase if there is a star on their receipt. So far, 219 of the first 264 customers have not received a star on their receipts. What is the experimental probability of winning a free gallon of milk?
A bag contains 7 green marbles, 9 red marbles, 10 orange marbles, 5 brown marbles, and 10 blue marbles. You choose a marble, replace it, and choose again. What is P(red, then blue)?
(1 point)
The probability of choosing a red marble followed by a blue marble is calculated by multiplying the probability of choosing a red marble on the first draw (9/41) by the probability of choosing a blue marble on the second draw (10/41), since the marble is replaced after the first draw:
P(red, then blue) = (9/41) × (10/41) = 90/1681
Therefore, the probability of choosing a red marble, replacing it, and then choosing a blue marble is 90/1681.
Each of two urns contains green balls and red balls. Urn I contains 10 green balls and 14 red balls. Urn II contains 4 green balls and 11 red balls. If a ball is drawn from each urn, what is P(red and red)?
(1 point)
The probability of drawing a red ball from urn I and a red ball from urn II is calculated by multiplying the probability of drawing a red ball from urn I (14/24) by the probability of drawing a red ball from urn II (11/15):
P(red and red) = (14/24) × (11/15) = 77/180
Therefore, the probability of drawing a red ball from each urn is 77/180.
If you spin the spinner below twice, what is P(vowel, then K)?
Without a visual of the spinner, we cannot determine the exact probabilities associated with the outcomes.
the right answer is 6/5 (6 green marbles out of 5 white marbles)
odds are different than probability ... favorable : unfavorable
the probability of green is ... 6/11
the odds of green is ... 6:5
so is it 6/5 or 6/11

i got 12/18 searching the answers one by one.
these should get you 100%
I made that reading error too this morning.
P green = 6/11
P not green = 5/11
6/11 / 5/11 = 6/5
it said odds,not probability. I made that reading mistake this morning too :)
