The 6,000 oranges harvested at an orange grove are a combination of valencia and navel oranges. the ratio of valencia oranges to navel oranges is 7 : 5. the owner of the orange grove finds that 1 in every 20 valencia oranges and 1 in every 25 navel oranges are rotten a) what fraction of oranges are not rotten? b) what is the probability that a randomly selected orange is a good orange? c) what is the probability that a randomly selected orange is a rotten valencia?

Step-by-step explanation:

Hard let me see

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.
