There are 4 green balls, 3 purple balls, 2 orange balls and 1 white ball in a box. one ball is randomly drawn and replaced, and then another ball is drawn. what is the probability of getting a green ball then an orange ball? 4/45 3/50 2/25 3/5

=2/25

Step-by-step explanation:

4/10*2/10

answer: 15

step-by-step explanation:

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.
