Sally made 500 gingerbread men. she sold 3/4 of them and gave away 2/5 of the remainder. how many gingerbread men did she give away?

As per the statement: Sally made 500 gingerbread men.

⇒Total gingerbread men made = 500

It is also given that: she sold 3/4 of them and gave away 2/5 of the remainder.

⇒ She sold = gingerbread men.

Remaining she left gingerbread men=

then,

she gave away = 2/5 of the remaining gingerbread men

⇒

Therefore, 50 gingerbread men did she give away.

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
