Jaime borrowed $2 from Alba. Jaime realized that Alba had previously borrowed $10 from him and asked her to return it back so he could buy a soccer ball that costs $12. Alba is happy to pay him the money back but tells Jaime that even if she paid him back right now, he will be short $4 from buying the ball. Who is correct, Jaime and or Alba? Please use a number sentence (like 1 + 1 = 2 or -1 + -1 = -2) as part of your evidence

Jaime

Step-by-step explanation:

Assuming he keeps the money he just borrowed

---} 2+10= $12

But if she requests her money back then she will be correct

---} -2+10= $8

step-by-step explanation:

85.560%

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
