Use algebra to determine the exact value, and check that
your answer is consistent with the graphical estimate.
46. (a) F(x) = (27x - x2)1/2
(b) G(x) = (27x – x2)1/3 + (1 - 1)
(c) H(x) = 27x^2 – x^4

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

2 over 5 and 4 over 15

don’t know last one sorry

this "question" looks more like a project is there any other info you can give me about this. it could be too complex for someone else to do on this website
