Ajar contains 3 blue marbles 6 red marbles 1 green marble and 2 black marbles. a marble is chosen at random from the jar and replaced. then another marble is chosen at random. find the probability of the first marble being red and the second marble being green

1/24

Step-by-step explanation:

the inequality is:

250c+180g≥950

step-by-step explanation:

let c denotes the number of days in a week   miyoko worked as a cryptographer.

and g denotes the number of days in a week she works as a geologist.

now we are given that she earns $250 for every day she works as a cryptographer,and earns $180 for every day she works as a geologist.

now miyoko's goal is to earn more than $950 this week.

hence, the inequality could be represented as:

250c+180g≥950
