A classroom has 14 blue chairs, 5 green chairs and 11 red chairs. If a chair is selected from the classroom at random, which color is most likely to be choses?

Blue, and with a 7/15 chance

Step-by-step explanation:

14+5+11=14+16=30

b=14/30=7/15

r=11/30

g=5/30=1/6

Have a nice day.

solution:

as, mean is defined as sum of all the observations divided by total number of observations.

and , median is mid value of the data whether arranged in ascending order or descending order.

consider, roadsters:

2,3,4,5,6,7,8,9

mean =

also, median= , because number of observations is even, so median is mean of two mid values.

now, coming to bandits

2,3,4,5,6

mean =  

median = 4, as number of observations is odd.

so, roadsters has greater median as well mean than bandits.

→option a is true about the repairs performed on 2 types of cars:

bandits have lower median and mean than roadsters.

what is the question?
