Ajar of alphabet tiles contains 10 unique consonant tiles and 5 unique vowel tiles. if 5 tiles are picked randomly, the probability that 3 are consonants and 2 are vowels is .

Step-by-step explanation:

This problem can easily be solved by using Hyper geometric Distribution :

Total number of tiles, N = 15

Number of tiles picked, n = 5

Number of successes, initially , k = 10

Number of successes for which to find, r = 3

Now, we need to calculate P(r = 3)

$5.41

step-by-step explanation:

$20 - $14.51 = $5.49.
