You select a card at random from the cards that make up the word replacement without replacing the card, you choose a second card. find the probability of choosing a vowel.

34/55

Step-by-step explanation:

Find the probability of the opposite; not a single vowel chosen.

So, the consonants are 7, so 7/11 times 6/10, which is 21/55.

Then, just 1 - 21/55 to get 34/55

hello from mrbilldoesmath!

answer:

a(n) - a(n-1) -3

discussion:

this ones a bit interesting. given a(n) = 5 - 3n consider this:

a(n-1) = 5 - 3(n-1)

          = (5 - 3n) + 3             => but a(n) = 5 - 3n, the first term

          = a(n)   + 3                 => subtract 3 from both sides

a(n-1) -3 = a(n)  

or

a(n) - a(n-1) -3

hans did not square the 40-unit side; he merely multiplied it by 2.   incorrect.
