There are 11 numbers on cards.
6 cards contain even numbers.
Answer: p(even) = 6/11
There is only one card with a 7. After the first card is picked and returned, there are 11 cards in the bag again.
p(even then 7) = p(even) * p(7) = 6/11 * 1/11 = 6/121
Answer: p(even then 7) = 6/121

Answer:
The cost of the one word is $30 .
Option (b) i.e 
is used to determine the total number of words in the ad mr.grant placed.
Step-by-step explanation:
Let us assume that the number of words in the ad be x.
As given
Mr.grant spent $8.40 to place an ad in the newspaper.
This price included one time fee of $6.00 plus $0.08 per word.
Than the equation becomes
8.40 = 6 .00 + 0.08x
Simplify the above
8.4 = 6 + 0.08x
8.4 - 6 = 0.08x
x = $30
Therefore the cost of the one word is $30 .
Option (b) i.e is used to determine the total number of words in the ad mr.grant placed.
(2.4)(a-0.2b+3.5c)= d. 2.4a 0.48b 8.4c
