Simplify the polynomials: 5xyx^3+7yxx^3–5x^2x^3–5x^2zx+3zx^3

Simplify each term: 5x^4y + 7x^4y - 5x^5 - 5x^3z + 3x^3z

Combine like terms: -5x^5 + 12x^4y -2x^3z  

That is the most simplified form.

If necessary, factor:

x^3(-5x^2+12xy-2z)

step-by-step explanation:

conditional probability is defined as:

p(a|b) = p(a∩b) / p(b)

in other words, the probability that a occurs, given that b has occurred = the probability that both a and b occur / the probability that b occurs.

in this example:

p(turns 64 | turns 44) = p(turns 64 & turns 44) / p(turns 44).

if someone turns 64, they must have already turned 44, so:

p(turns 64 | turns 44) = p(turns 64) / p(turns 44)

on page 42, we see that of the original 100,000, 94944 turn 44, and 81234 turn 64.   therefore:

p(turns 64 | turns 44) = 81234 / 94944

p(turns 64 | turns 44) = 0.85560
