Step-by-step explanation:
There are four possible values of X: 0 rats show side effects, 1 rat shows side effects, 2 rats show side effects, or all 3 rats show side effects.
Probability X = 0:
P = (1 − 0.5) (1 − 0.4) (1 − 0.3)
P = 0.21
Probability X = 1:
P = (0.5) (1 − 0.4) (1 − 0.3) + (1 − 0.5) (0.4) (1 − 0.3) + (1 − 0.5) (1 − 0.4) (0.3)
P = 0.44
Probability X = 2:
P = (0.5) (0.4) (1 − 0.3) + (0.5) (1 − 0.4) (0.3) + (1 − 0.5) (0.4) (0.3)
P = 0.29
Probability X = 3:
P = (0.5) (0.4) (0.3)
P = 0.06
Answer: 2.0 miles= 10560 feet
Step-by-step explanation:
Answer: 10
Step-by-step explanation:
16 x 5/8
reduce the numbers to 2 x 5
cross out 16 and 8 and you have 5 left, 16 divided by 8 = 2
2 x 5 = 10
hope this makes sense and helps you :)
The correct answer is 4x to the third power.
The event by definition that covers the entire sample space of the experiment is;
<em><u>The number is even or less than 12</u></em>
We are given the numbers in the set as;
set {2, 3, 4,... 10}.
Now, the numbers in the set are even and odd numbers from 2 to 10 with 10 being the highest and 2 being the lowest.
Thus the event that covers this sample space is simply a set of numbers that are even or less than 12.
