Answer:
Step-by-step explanation:
Sample space is 36C4
Now, we want to know all of the combinations that have 1 digit in it.
So, we can have one here:
1XXX
X1XX
XX1X
XXX1
But we have 10 different digits to choose from. So, we need to introduce the combination term, nCr, where n is a list of all digits and r is how many we want.
Since we only want one, we will need 10C1 for the number of digits. But we need to choose three lowercases, so it becomes 10C1 × 26C3
Since it's a probability question, we need to divide that by our sample space, 36C4, and our percentage becomes 44%
Answer: =248x
Step-by-step explanation: Hope this help :D
Let's simplify step-by-step.
4x(10)+2x(104)
=40x+208x
Combine Like Terms:
=40x+208x
=(40x+208x)
=248x
It took him 7 minutes to run each mile.
Firstly, covert the time into minutes.
3 * 60 = 180 minutes
180 + 2 = 182 minutes
Now in order to find how long he ran each mile,
divide 182 by 26
182/26 = 7 minutes
