Suppose that 45% of people have dogs. If two people are randomly chosen, what is the probability that they both have a dog

Step-by-step explanation:

Given

Required

Probability of two people having dog

First, we have to convert the given parameter to decimal

Let P(Dogs) represent the required probability;

This is calculated as thus;

P(Dogs) = Probability of first person having a dog * Probability of second person having a dog

Hence, the probability of 2 people having a dog is

d

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
