Hey! I can explain exactly how to do this. First off, we need to find slope to do slope intercept form, y = mx+b. To do this, we need two points, and use the formula y2-y1/x2-x1. Because I can't see the points clearly, I can give you an example. If we had (3,5) and (5,6), we would have 6-5/5-3, getting us 1/2 as our slope. Next, we need the y-intercept, or b. The way we find it is we see at which point does the like cross the y axis, the one that goes up and down. This point will always be (0, and then the y value) as there is no x value. Make sure to do this for all of these, and always write it in slope intercept. Message me if you need any more help! I'm here if you need me.

Find the probability of picking 4 consonant and 1 vowels when 5 letters are picked (without replacement) from a set of alphabet
Ganezh [65]

The required probability is 0.45

We have total 26 letters in english, of which 21 are consonants and 5 are vowels.

According to the question, we have to select 5 of them of which 4 will be consonants and 1 will be vowel.

Suppose we want to have the vowel in the first selection, so the probability of picking a vowel is equal to the quotient between the number of vowels and the number of total number of letters.

So the probability is 5/26

Now, a letter has been selected, so in the set, we have 25 letters left.

In the next 4 selections, we must select consonants.

In the second selection the probability is 21/25

In the third selection the probability is 20/24

In the fourth selection the probability is 19/23

In the last selection the probability is 18/22

So, the probability is (5/26)×(21/25)×(20/24)×(19/23)×(18/22)

Now, remember that we take that the vowel must be in the first place, but it can be in any five places, so if we add the permutations of the vowel letter we have,

P = 5×(5/26)×(21/25)×(20/24)×(19/23)×(18/22) = 0.45
