Sample spaces quiz 1
You roll a standard dice once.Find P(0)
duh - p(0) = 0
i have a question
Sure! What's your question?
from a barrel of colored marbles you randomly pick 7 blue 5 yellow 8 red 4 green 6 purple marbles
find the experimental probability of randomly piking a marble that is not yellow wright your answer in simplest from
1) 1/30
2) 3/6
3) 2/15
4) 1/6
what is the answer
The total number of marbles in the barrel is:
7 blue + 5 yellow + 8 red + 4 green + 6 purple = 30
The number of marbles that are not yellow is:
30 - 5 = 25
The experimental probability of randomly picking a marble that is not yellow is:
25/30 = 5/6
Therefore, the answer is not one of the options given. The correct answer is:
5/6
from a barrel of colored marbles you randomly pick 7 blue 5 yellow 8 red 4 green 6 purple marbles
find the experimental probability of randomly piking a marble that is ether green or purple wright your answer in simplest from
1/10
1/5
1/3
2/15
The total number of marbles in the barrel again is:
7 blue + 5 yellow + 8 red + 4 green + 6 purple = 30
The number of marbles that are green or purple is:
4 green + 6 purple = 10
The experimental probability of randomly picking a green or purple marble is:
10/30 = 1/3
Therefore, the answer is option (C) - 1/3.
You mix the letters S,E,M,I,T,R,O,P,I,C,A and L thoroughly.
Without looking you draw one letter. Find the probability that you select a vowel. Write your answer as a fraction in simplest form
There are 15 letters in total. We need to count the number of vowels in the set {S,E,M,I,T,R,O,P,I,C,A,L}. There are 5 vowels: E, I, O, I, and A.
The probability of selecting a vowel is the number of vowels in the set over the total number of letters:
5/15 = 1/3
Therefore, the probability of selecting a vowel is 1/3.
