Alfredo has different colored spiral notebooks in his backpack. Which of the following models could be used to simulate a 1 in 3 chance of Alfredo randomly selecting a red spiral from his backpack?

Answer:

the fourth option

Step-by-step explanation:

Probability calculates the likelihood of an event occurring. The likelihood of the event occurring lies between 0 and 1. It is zero if the event does not occur and 1 if the event occurs.

For example, the probability that it would rain on Friday is between o and 1. If it rains, a value of one is attached to the event. If it doesn't a value of zero is attached to the event.

Probability of choosing a red spiral = number of red spiral / total sum of spirals in the bag

1st option = 2 / 4 = 1/2

2nd option = 4/8 = 1/2

3rd option = 2/3

4th option = 2/6 = 1/3

the fourth option is correct

The school counselors are planning the numbers of different math classes for these students when they enter eighth grade. Which statement best describes the plan they should follow, based on the information shown?
A


School 1 should have a greater variety of math classes, since the interquartile range is much smaller than at school 2.

B


School 2 should have a greater variety of math classes, since the median is higher than at school 1.

C


School 2 should have a greater variety of math classes, since the interquartile range is much greater than at school 1.
