When trying to find the probability of drawing a violet marble from a jar containing 9 red, 4 brown, 10 yellow, and 8 violet marbles, how many desired outcomes are there?

When trying to find the probability of drawing a violet marble from a jar containing 9 red, 4 brown, 10 yellow, and 8 violet marbles, how many desired outcomes are there?  Solution: We need to find the probability  of drawing a voilet marble when there are 8 voilet marbles. Drawing any of thr voilet marble will be a favourable or desired outcome.  As, there are 8 violet marbles and getting any of the voilet marble is a desired outcome . So, the desired outcomes are 8.  Probability  is desired outcome /total outcome. There are 8 voilet marbles and  there are 31 marvels. So probability of getting a voilet marble=8/31  desired oucomes=8

725 parts per hour.

step-by-step explanation:

hi there, this answer is actually really simple.

you can set it up as 1450/2 or 3625/5 to find the answer.

they want to know how much per hour is being made, so you just divide.

1450/2=725.

and that's how many are produced per hour.

hope this . : )

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%
