Answer:
The probability that none of the three shoes selected are green = 64/125
Step-by-step explanation:
If we have 1/5 of shoes being green, then the number of non-green shoes = 1-1/5 = 4/5
Now, this is a probability with replacement.
probability of the first shoe since it’s not green = 4/5
probability of second shoes since it’s not green = 4/5
probability of third shoe since it’s not green = 4/5
Now, the probability that none of the shoes are green = 4/5 * 4/5 * 4/5 = 64/125
It is on the ten thousands value
Yes he is correct because 1/3 can be shown on a number line
Answer:
Probability that she or he bought lunch in the cafeteria and chose pizza as an entree = 12/100 =0.12 = 12%
Explanation:
Let number of students be 100.
At Taylor Street School, 40% of the students bought lunch in the cafeteria today
Number of students bought lunch = 100 x 40/100 = 40
Of the students who bought lunch in the cafeteria today, 30% chose pizza as their entree
Number of students bought pizza = 40 x 30/100 = 12.
Probability of an outcome = Number of favorable outcome/ Total number of outcome
Probability that she or he bought lunch in the cafeteria and chose pizza as an entree = Number of students bought pizza/Total number of students
= 12/100 =0.12 = 12%
Probability that she or he bought lunch in the cafeteria and chose pizza as an entree = 12/100 =0.12 = 12%
