A box is filled with 9 red crayons, 5 blue crayons, and 8 yellow crayons. A crayon is chosen at random from the box. Find the probability that it is a blue or a yellow crayon. Write your answer as a fraction in simplest form.

13/22

Step-by-step explanation:

Number of red crayons = 9

Number of blue crayons = 5

Number of yellow crayons = 8

Total number of crayons = 9+5+8 = 22

The probability of selecting either ia blue or a yellow crayon will be:

= 5/22 + 8/22

= 13/22

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
