Answer: first: 1/6 second dice: 4/6
Step-by-step explanation:
So we know that a dice have the numbers 1,2,3,4,5, and 6 .
So the the probability that first die rolled 2 is 1/6 because there appears only on 2 .
and the probability that the second dice rolled a number greater than 2 is 4/6 or 2/3 because there are 4 numbers greater than 2 out of the 6 total .
Answer:
Area under the normal curve: 0.6915.
69.15% probability of putting less than 24 ounces in a cup.
Step-by-step explanation:
Problems of normally distributed samples are solved using the z-score formula.
In a set with mean
and standard deviation
, the zscore of a measure X is given by:

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
In this problem, we have that:

You have been asked to calculate the probability of putting less than 24 ounces in a cup.
pvalue of Z when X = 24. So



has a pvalue of 0.6915
Area under the normal curve: 0.6915.
69.15% probability of putting less than 24 ounces in a cup.
