2a^2-32

2*a^2-2*16

2*(a^2-16)

but we have a Difference of two square

x^2-y^2=(x+y)*(x-y)

now you can see it very well

2*(a^2-4^2)

so

\boxed{\boxed{2*(a-4)*(a+4)}}

Sam intends to roll a six sided cube 100 times. What is the probability model he can use to predict whether or not each roll wil
bekas [8.4K]

The outcomes of rolling fair six sided die is \{1,2,3,4,5,6\}. The prime numbers in the above outcomes are \{2,3,5\}. The probability of not rolling a prime number is p=\frac{3}{6}= 0.5.

Each trial is independent.

In the given experiment of 100 trials, the binomial probability model can be used to predict the number of occurrence of non-prime numbers (X). The probability mass function is

P(X=x)=C(100,x)p^x(1-p)^{100-x},x=0,1,2,3,...,100. Since p=0.5,1-p=0.5

P(X=x)=C(100,x)0.5^x(0.5)^{100-x},x=0,1,2,3,...,100 \\ P(X=x)=C(100,x)(0.5)^{100},x=0,1,2,3,...,100
