4/8

Answer 1

The answers to your questions are as follows :

1. The situation with a probability closest or equal to 0 is rolling a number: (A) greater than 5.
2. The model which shows the probability of choosing a multiple of 4 is: ( B )  $\frac{2}{10}$ (2/10)
3. The only survey that would not be valid with a sample of seventh-grade classmates is : ( B ) Bank that offer the most services.
4. The probability of choosing a red marble, then a white marble if the marbles are replaced is : ( A ) 7/10.
5. The probability of spinning the following. P(not 7) = 7/8

Meaning of Probability

Probability is a branch of mathematics that deals with the degree of occurrence of an event.

1) The situation with a probability closest or equal to 0 is rolling a number: (A) greater than 5.

Because: there is only one number greater than 5 in that list (which is 6)

2) The model which shows the probability of choosing a multiple of 4 is: ( B )  $\frac{2}{10}$ (2/10)

Because: there are only two multiples of 4 that can be picked from number 1-10

3) The only survey that would not be valid with a sample of seventh-grade classmates is :  Bank that offer the most services.

Because: they are not working and might have little or no idea about banking services.

4) The probability of choosing a red marble, then a white marble if the marbles are replaced is : 7/10.

where the probability of picking a red marble is =  $\frac{3}{10}$

The probability of picking a white marble is = $\frac{4}{10}$

since the marbles were replaced : $\frac{3}{10}$ + $\frac{4}{10}$ = $\frac{7}{10}$

5) The probability of spinning the following. P(not 7) = 7/8

The probablity of picking a 7 is = $\frac{1}{8}$

The probability of not is = 1 - probability of picking 7

1 - $\frac{1}{8}$ = $\frac{7}{8}$
