AT YOUR NEW JOB AT THE COFFEE SHOP, YOU SOLD 42 LARGE
COFFEES AND 54 SMALL COFFEES.
WHAT WAS THE RATIO OF LARGE
TO SMALL COFFEES YOU SOLD?

106 : 84

Step-by-step explanation:

53 : 42 = 106 : 84

The ratio is already in lowest terms so found I an equivalent ratio by multiplying both terms by 2.

9514 1404 393

  7 : 9

Step-by-step explanation:

The ratio of interest is ...

  large coffees : small coffees = 42 : 54 = 7 : 9

think about it deeply and passionately about this property

i am sorry

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
