Answer:
Probability that one of them is mathematics and other two are either physics or history books = 0.51
Step-by-step explanation:
Given - A student needs to select 3 books from 3 different mathematics, 3 different physics and 1 history books.
To find - What is the probability one of them is mathematics and other two are either physics or history books ?
Solution -
Given that,
A student needs to select 3 books from 3 different mathematics, 3 different physics and 1 history books.
So,
Total number of books = 3 + 3 + 1 = 7
The student has to select 3 books
So, Total number of ways = = 35
So,
Probability that one of them is mathematics and other two are either physics or history books is -
=
=
=
= 0.51
⇒Probability that one of them is mathematics and other two are either physics or history books = 0.51
When dividing 250,000 by 100, the digits in the quotient move by 2 places to the right.
<u>Step-by-Step explanation:</u>
Here we have , to find out that When dividing 250,000 by 100, the digits in the quotient move how many places to the right . Let's find out:
⇒ dividing 250,000 by 100
⇒ 250,000 / 100
⇒
⇒
⇒
Initially we had 250,000 of 6 digits and now after dividing 250,000 by 100, we have 2500 of 4 digits ! So , Number of places quotient shift to right is:
⇒
⇒
Therefore, When dividing 250,000 by 100, the digits in the quotient move by 2 places to the right.
