Make use of prime factorizations:
Both terms have a common factor of 
:
- - -
The second one is not true! We can write
Both terms have a common factor of 
:
Since 
, and 
, we'd still have to show that 
is a multiple of 6. This is impossible, because 
and there is no multiple of 2 that can be factored out.
The probability that the first two votes drawn are both for candidate a is given by:
3C2/5C2 = 3/10
Having drawn two votes for candidate a on the first two draws, there are 2 votes for candidate b and one vote for candidate a remaining. The probability that a vote for candidate b will be drawn on the third draw is:
2/3.
After the first three draws, there reains one vote for candidate a and one vote for candidate b. The probability that a vote for candidate a will be drawn on the fourth draw is:
1/2.
The probability of the ordering aabab is therefore given by:
The answer is: 0.1.
so the missing term in the denominator is 7^(-22)
ok done. Thank to me :>
The roots of the quadratic equation 3y² + 3(4y² - 2) is ± √(1/7).
<h3>What is a quadratic equaton?</h3>
A quadratic equation is an algebraic expression in the form of variables and constants.
A quadratic equation has two roots as its degree is two.
Given, 3y² + 3(4y² - 2).
3y² + 12y² - 2.
14y² - 2.
Let 14y² - 2 = 0.
14y² = 2.
y² = (2/14).
y = ± √(2/14) Or ± √(2/2×7) Or ± √(1/7).
