Two thousand adults were randomly selected and asked whether they had shopped online in the previous week. Their responses
are in the table. Are the events F-'is female and S have shopped' independent? Why or why not?
Yes; because P(F & S) - P(F). P(S),
No; because P(F & S) + P(F). P(S)
Yes; because P(F & S) - P(F) + P(S)
No; because P(F & S) HP(F) + P(S)

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
