Answer: 0.500
Step-by-step explanation:
Given : A normal distribution has a mean
of 10 and a standard deviation
of 1.
Let x be a random variable that represents numbers .
The probability of selecting a number that is at most 10 will be

As the area occupied by standard normal curve less than equal to 0 = 0.500
So, required probability = 0.500
Answer: Excuse me, what do you mean "and 6 is 5?"
Step-by-step explanation:
To be honest, I got 5, because the total is 25, divide that by 5, and you get 5. Or I also got 6, for WORKING tv sets, only kids with tv sets would be included, so it would be 24 divided by 4.
Step-by-step explanation:
picking 3 consonants and 2 vowels when 5 letters are picked (without replacement) from a set of alphabet tiles.
There are 26 letters in alphabet
number of consonants = 21 and number of vowels = 5
We need to pick 3 consonants from 21 consonants
Probability of picking 1 consonant from 26 alphabets = 21/ 26
after picking 1 consonant then number of consonant becomes 20
Probability of picking second consonant from 25 alphabets = 20/ 25
Probability of picking third consonant from 24 alphabets = 19/ 24
We need to pick 2 vowels from 5 vowels
Probability of picking 1 vowel from remaining 23 alphabets = 5/ 23
Probability of picking second vowel from remaining 22 alphabets = 4/ 22
Now multiply all the probabilities

= 0.02022
Answer:
454 grams
Step-by-step explanation:
453.592 grams in 1 pound.
2 pounds= 453.592*2
