Jerry mixes the letters F,P,M,M,M,F,P and J thorough. Without looking Amanda draws one letter. Expressed as a fraction, decimal and percentage. What is the probability that J will NOT be the letter Amanda selects?
A.7/8, 0.875, 87.5%
B.5/8, 0.625, 62.5%
C.1/8 , 0.125, 12.5%
D.8/7, 1.14, 11.4%
And your answer is?
P(j) = 1/8
so
P(not j) = 1-1/8 = 7/8
My answer is D i think. But im not sure
NO, a probability greater than 1 means there is greater than 100% chance it will happen !!!!
That is the second time this morning I have seen a probability >1
That itself is very low probability.
Well, let's see. The total number of letters is 7, and there is only 1 letter J. So, the probability of selecting J is 1/7.
Now, we want to find the probability that J will NOT be selected. Since there is only 1 J, the probability of selecting any other letter is 6/7.
So, the probability that J will NOT be selected can be expressed as 6/7, which is equivalent to 0.857 in decimal form and 85.7% in percentage form.
Since none of the options provided match these values, I'm afraid I can't give you a direct answer. But I hope I was able to help you in understanding the concept of probability!
To find the probability that J will NOT be the letter Amanda selects, we need to determine the number of favorable outcomes (where J is not selected) and divide it by the total number of possible outcomes.
First, let's count the number of favorable outcomes. Since we want to exclude J, we need to count the number of non-J letters in the mix. Among the given letters (F, P, M, M, M, F, P, and J), there are 7 letters that are not J (F, P, M, M, M, F, and P). Therefore, there are 7 favorable outcomes.
Now let's count the total number of possible outcomes. We have a total of 8 letters (F, P, M, M, M, F, P, and J) in the mix. Hence, there are 8 possible outcomes.
To find the probability, we divide the number of favorable outcomes by the total number of possible outcomes:
Probability = favorable outcomes / total outcomes = 7/8
Now let's express this probability as a decimal. To do this, divide the numerator (7) by the denominator (8):
Decimal = 7/8 ≈ 0.875
Lastly, let's express the probability as a percentage. Multiply the decimal by 100 to find the percentage:
Percentage = 0.875 × 100 = 87.5%
Therefore, the correct answer is A. 7/8, 0.875, 87.5%.
