What is the probability of getting a license plate that has a repeated letter or digit if you live in a state in which license plates have two letters followed by four numerals? (Round your answer to one decimal place.)

Therefore, the probability is  P=0.5.

Step-by-step explanation:

We calculate the the probability of getting a license plate that has a repeated letter or digit if you live in a state in which license plates have two letters followed by four numerals.

We will calculate the required probability through complement. First, we find the probability that a license plate has all different the letters and all different the numbers.

We calculate the number of possible combinations:

We calculate  the number of favorable combinations:

Therefore, the probability is

Now, we get

Therefore, the probability is  P=0.5.

50-38=12

step-by-step explanation:

30 miles

step-by-step explanation:

we know that 60 seconds equals 1 minute and 60 minutes 1 hour

44 ft       60 sec     60 min     158400   ft

  *   *   =

1 sec       1 min       1 hour         hour

we know that there are 5280 ft per mile

158400   ft       1 mile         30 miles

  *   =

1   hour               5280 ft     1 hour

so in 1 hour   it can travel 30 miles
