Answer: Create intervals, then count the number of countries that fall in each interval.
When you create a frequency table, you have set intervals. In this case, our small number is close to 0 and our largest number is 4.5. We could create an interval for each number. Then, count the number of countries in each.
It would look like: Interval Frequency 0-0.99 1 1-1.99 5 2-2.99 5 3-3.99 2 4-4.99 1
There are 4 green marbles and 6 red marbles, making 10 green or red marbles. The probability of drawing a red or a green marble is then 10/15 total marbles, which can be simplified to 2/3 by dividing the numerator and denominator each by 5.
Because for 4 weeks he saved 35% of 200$ which would be 70 and 70+70+70+70 is 280$ and then he saved 175 dollars on the 5th week because 7/8 of 200 is 175 so 280+175= 455
