A card is chosen at random from a standard deck of 52 playing cards. What is the probability that the card chosen is a queen?

Probability = 4/52

= 1 / 13

Step-by-step explanation:

Total number of cards = 52

Prob of choosing a queen

In a deck of card there are 4 queens

Probability = 4/52

= 1 / 13

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

853.3
