Answer:

There are a total of possible 1820 results.

Step-by-step explanation:

Since there are two competitions, one for boys and one for girls, and we want all the possible results we will calculate the possible combinations for the boys and multiply them by the possible combinations for the girls. This is shown below:

Boys = \frac{15!}{3!(15 - 3)!} = \frac{15!}{3!12!} = \frac{15*14*13*12!}{3!12!}\\Boys = \frac{15*14*13}{3*2*1}\\Boys = \frac{15*14*13}{3*2*1}\\Boys = 455

Girls = \frac{4!}{3!*(4 - 3)!}\\Girls = \frac{4*3!}{3!}\\Girls = 4

Total number of possible results:

results = 4*455\\results = 1820

A password contains six digits, such as 174668. How many different passwords can be formed
STALIN [3.7K]

Answer: The number of different passwords can be formed = 1,000,000

Step-by-step explanation:

In general total digits = 10  [ from 0 to 9]

If a password contains 6 digits, then by fundamental principal of counting, the total number of different passwords =10\times10 \times10\times10\times10\times10=10^6=1000000

Hence, the number of different passwords can be formed = 1,000,000
