4^2-2 X 3 + 6 = ? SOLVE with PEMDAS

my son has had problems with algebra and tbh I don't know how to do it either i was hoping someone on here can help!

4^2 -2×3+6=16 is your answer

b

step-by-step explanation:

u take $75 minus $60.the anwer/original($75)multiply by 100

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
