In Social Studies, Mrs. McInteer picks a student to write a homework problem on the board. Here are the probabilities that given students will be chosen.
P(Johnny)=0.62
P(Ruben)=0.12
P(Apple)=0.15
P(Yolanda)=0.36
Select the true statement below.
It is likely that Apple will be chosen.
it is very likely that Yolanda will be chosen
Yolanda is 3 times as likely to be chosen as Ruben
It is unlikely that Johnny will be chosen

The table shows outcomes of this spinner with five equal sections, orange, yellow,
purple, green and blue.
Orange=25, Yellow=35, Purple=30, Green=35, Blue=25
Which statement is true?
The arrow is expected to land on orange 5 times if it is spun 30 times
The arrow is expected to land on the purple 2 times if it is spun 20 times
The arrow is expected to land on blue 9 times if it is spun 50 times
The arrow is expected to land on yellow or green 15 times it is spun 60 times.
A spinner has eight equally sized sections labeled 1 through 8. A uniform probability model can be constructed to represent the probabilities of outcomes. use the model to calculate the probability of the spinner landing on an even number.

Half of the students at Sequoia have first lunch and half have second lunch. If students are randomly selected with replacement, then how many students would need to be selected before three of them have first lunch? To simulate this situation, Carl uses a coin. He lets heads (H) represent students with first lunch and tails (T) represent students with second lunch. Which statements are true? Choose all that are correct.
For each trial, Carl should record the number of flips until three heads appear
Each trial will require exactly 6 coin flips
A trial with the results TTHTHTH would mean that 7 students had to be selected to have 3 students with first lunch
A trial would be represented by 3 coin flips
Each of 20 students in a science class perform the same experiment that involves measuring the temperature of a solution. Decide if each option below is a valid inference.
Averaging the temperature measured by 5 class members whose names were picked from a stack of shuffled cards
Averaging the temperatures measured by the six students with the highest scores on the last science test.
Averaging the temperature measured by every fifth student who entered the classroom that day.
Averaging the temperatures measured by five students who always work together as a lab team.
