Probabilty Helpppp. i dont qet it?

7. P(A) is the probability of selecting the letter A. Since there are a total of 3 As and 8 total letters, the probability of selecting A is: P(A) = 3/8

8. P(R) = 1/8

10. P( K or N) = 2/8 = 1/4

11. P(vowel) = 3/8

12. P(consonant) = 5/8

Probability is just another way of doing fractions.

The probability of pulling an A would be 3/8, because there are three A's, and eight letters in all.

R would be 1/8 because there is only one R in the eight letter word.

K or N would be 2/8 because there is one K, and one N, add those together and it's two out of the eight letter word.

Probability for a vowel is 3/8, because A is the only vowel in the word and we'd already established that the probability for an A was 3/8.

Probability for a consonant is 5/8 because if it isn't a vowel, then it's a consonant, so subtract the three A's from eight and you get five consonants out of eight letters.

u take the amount possible and put that under the amount that it asks for, like since Arkansas has 8 letters you put that on the bottom of a fraction. in #7 it asks for the probability of A in the word Arkansas which is shown as P(A), and said as the probability of A in Arkansas, so you count how many times A appears in the word Arkansas, since appears 3 times you put 3 over 8 in a fraction or whatever it form it asks u to answer it in so it looks like the without the slant 3/8

#7= 3/8

#8= 1/8

#10= 1/4(simplified) since 2/8 and 1/4 have the same value

#11= 3/8

#12= 5/8

7. 3/8 = .37%

8. 1/8 = .13%

10. 2/8 = .25%

11. 3/8 = .37%

12. 5/8 = .63%

You take whatever the letter is i.e. "A", and divide that by 8, since there are 8 letters in ARKANSAS

3/8

1/8

2/8

3/8

5/8
