4) Students in a poetry class are writing poems for their portfolios. The teacher wants them to write stanzas with certain numbers of lines each. Bruce wrote 3 short stanzas and 2 long stanzas, for a
total of 46 lines. Jane wrote 9 short stanzas and 2 long stanzas, for a total of 94 lines. How many
lines do the two sizes of stanzas contain?
How many lines does the short stanza contain?
How many lines does the long stanza contain?

your answer would be 12

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

multiple all that
