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