a teacher wants to give 3 markers to each of her 25 students .Markers come in packages of 8.How many packages of markers will the teacher need?

10 packs of markers

Step-by-step explanation:

3 x 25 = 75 markers she will need for her whole class

75 / 8 = 9.4 packages needed to get 75 markers, but since you cant buy have of a pack you round up so she will have enough for her class and a couple extra.

answer:   rlly

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
