In a lottery, 6 numbers are randomly sampled without replacement from the integers 1 to 38. Their order of selection is not imp
1 answer:
Answer: Our required probability is 0.328.
Step-by-step explanation:
Since we have given that
there is number on the lottery is from 1 to 38.
6 numbers are selected.
We need to find the probability of holding a ticket that has zero winning numbers out of the 6 numbers selected for the winning ticket.
So, it should be other than 6 numbers.
Remaining numbers = 38-6 = 32
So, our probability becomes
Hence, our required probability is 0.328.

I'm assuming you're looking to find the expanded form of the number?
This number is in scientific notation. The easiest way to convert it to a normal number is to move the decimal place 14 to the right. I've attached a picture showing how to do this. You should get 630,000,000,000,000
There's a faster way to do this - notice that you need to move the decimal 14 to the right, and there's one number already after the decimal place. Therefore, 13 places will be filled with zeros. So, just write out 63 and add 13 zeros.
