A money box contains four $2 coins, seven $1
coins, twelve 50 cent coins and twenty two 20
cent coins. Christie chooses a coin at random.
Find the probability she chooses a coin that
is worth at most $1.

13/15

Step-by-step explanation:

So add the total amount of coins:  4 + 7 + 12 + 22 = 45

Since the only coins that are at most $1 are:  The $1 coins, 50 cent coins, and the 20 cent coins.  That is a total of 7 + 12 + 20 = 39

39/45

13/15

 13/15

the expression (1.26)2t reveals the approximate rate of increases in the number of plants semiannually.
