8)If there are 4 yellow, 2 blue, 1 red, and 3 green marbles in a bag, what is the
probability you choose a blue marble at random, P(blue)?
What is the Pſyellow)?

P(blue)=1/5. P(yellow)=2/5.

Step-by-step explanation: First find the total number of marbles. 4+1+2+3=10. To find the probability of blue marbles, use this equation (number of blue marbles (2) / total number of marbles(10) ). 2/10=1/5.

To find the probability of yellow marbles do this equation (number of yellow marbles (4) / total number of marbles (10) ). 4/10=2/5.

0/5 is 0, 2/0 is undefined, and 0/0 is indeterminate.

step-by-step explanation:

hope my answer has you!

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
