For this you have to make two proportions that are and set them equal to each other.
The first proportion represents the percent of people who like silver as their favorite car color
Since this is a circle graph the whole will always be 100 because percents are always taken out of 100
The part would be 10 because only 10% out of the 100% like silver
The second proportion is the people that represent the response.
350 would be the whole because that is the total amount of people surveyed
The part is unknown and what you are solving for.
Here is how the proportion should look like:
Cross multiply (If you don't know what this is look at the image below to see my work)
The cross multiplication will give you:
3500 = 100x
Isolate x by dividing 100 to both sides
3500/100 = 100x/100
35 = x
This means that 35 people out of the 350 surveyed like silver cars

Answer:
Events 2,4 and 5 have probabilities greater than 0.5
Step-by-step explanation:
They are 10 balls combined: 2blue, 3 red and 5 white with the probabilities:
#We calculate the probabilities to check which events have a probability greater than 1/5=0.2
#choosing 1 blue marble
#choosing 1 red marble
#choosing 1 red marble, not replacing it,
#choosing 1 white marble, replacing it, and choosing another white marble
#choosing 1 white marble
Hence, from our calculations, events 2,4 and 5 have probabilities greater than 0.5
