Keith_Richards [23]

Answer:

$(3a-y)(3a+y)$

Step-by-step explanation:

This is a difference of squares that has the form and factors to:

$a^2x^2-b^2 = (ax-b)(ax+b)$

The five posters made for spirit week are being hung in the front hall. What is the probability the largest poster will be in th

Leto [7]

Answer:

1/20 or 0.05

Step-by-step explanation:

Assuming that all five posters are different, the number of ways to randomly place those posters is given by:

$N=5*4*3*2*1 = 120\ ways$

If we want the largest to be in the center and the next largest to be on its left, two poster will have a set position and only three could be randomized:

$n=3*2*1*1*1=6\ ways$

Therefore, the probability is:

$P=\frac{n}{N}=\frac{6}{120} =\frac{1}{20} =0.05$

The probability is 1/20 or 0.05.
