The two events are independent, so the probability of both happening is the product of the two.
Probability of picking an even number is 3/6=1/2
Probability of picking the letter A is 1/3 = 1/3
Product of probability of two independent events = (1/2)(1./3)=1/6.
Answer:
29.49% probability that a production time is between 9.7 and 12 minutes
Step-by-step explanation:
An uniform probability is a case of probability in which each outcome is equally as likely.
For this situation, we have a lower limit of the distribution that we call a and an upper limit that we call b.
The probability that we find a value X between c and d, in which d is greater than c, is given by the following formula.
![P(c \leq X \leq d) = \frac{d - c}{b-a}](https://tex.z-dn.net/?f=P%28c%20%5Cleq%20X%20%5Cleq%20d%29%20%3D%20%5Cfrac%7Bd%20-%20c%7D%7Bb-a%7D)
Production times are evenly distributed between 8 and 15.8 minutes and production times are never outside of this interval.
This means that ![a = 8, b = 15.8](https://tex.z-dn.net/?f=a%20%3D%208%2C%20b%20%3D%2015.8)
What is the probability that a production time is between 9.7 and 12 minutes?
.
So
![P(c \leq X \leq d) = \frac{d - c}{b-a}](https://tex.z-dn.net/?f=P%28c%20%5Cleq%20X%20%5Cleq%20d%29%20%3D%20%5Cfrac%7Bd%20-%20c%7D%7Bb-a%7D)
![P(9.7 \leq X \leq 12) = \frac{12 - 9.7}{15.8 - 8} = 0.2949](https://tex.z-dn.net/?f=P%289.7%20%5Cleq%20X%20%5Cleq%2012%29%20%3D%20%5Cfrac%7B12%20-%209.7%7D%7B15.8%20-%208%7D%20%3D%200.2949)
29.49% probability that a production time is between 9.7 and 12 minutes
I think it’s B... i’m not 100% sure but i’m like 90% positive it is.
Answer:

A null set is a set which has no elements in it. So, the cardinal number of a null set is zero.
Answer:
Hi! so i cant see the problem only the question so il try to help.
Step-by-step explanation:
so look at your problem and follow the line that links P, Q and R
follow those letters and see whether its straight in a curved line or its curved in a different way.
hope this helps :p
