Answer:
360
Step-by-step explanation:
Given
Digits: 0 to 5
Required
Number of 4 digit passcode that can be generated.
First, we need to get the number of usable digits.
Digits 0 to 5 = 0,1,2,3,4,5
Number of digits = 6
To make a 4 digit passcode;
The first digit can be taken from any of 6 digits
The second digit, any of the remaining 5 digits
The third digit, any of the remaining 4 digits
The fourth digit, any of the remaining 3 digits
Number of passcode = 6 * 5 * 4 * 3
Number of passcode = 360

Answer:
the probability is 2/9
Step-by-step explanation:
Assuming the coins are randomly selected, the probability of pulling a dime first is the number of dimes (4) divided by the total number of coins (10).
p(dime first) = 4/10 = 2/5
Then, having drawn a dime, there are 9 coins left, of which 5 are nickels. The probability of randomly choosing a nickel is 5/9.
The joint probability of these two events occurring sequentially is the product of their probabilities:
p(dime then nickel) = (2/5)×(5/9) = 2/9
_____
<em>Alternate solution</em>
You can go at this another way. You can list all the pairs of coins that can be drawn. There are 90 of them: 10 first coins and, for each of those, 9 coins that can be chosen second. Of these 90 possibilities, there are 4 dimes that can be chosen first, and 5 nickels that can be chosen second, for a total of 20 possible dime-nickel choices out of the 90 total possible outcomes.
p(dime/nickel) = 20/90 = 2/9
