Three workers at a fast food restaurant pack the take-out chicken dinners. john packs 45% of the dinners, mary packs 25% of the dinners and sue packs the remaining dinners. of the dinners john packs 4% do not include a salt packet. if mary packs the dinner 2% of the time the salt is omitted. lastly, 3% of the dinners do not include salt if sue does the packing. if you find there is not salt in your purchased dinner what is the probability that mary packed your dinner?

0.5625

Step-by-step explanation:

If John packed the dinner

probability of salt less dinner==0.018

If Mary packed the dinner

probability  of salt-less dinner ==0.005

If sue packed the dinner

probability  of salt-less dinner ==0.009

Total proportion of salt-less dinner=0.032

probability that dinner is salt-less and mary packed it==0.5625

the ratio of white tiles to blue tiles is 48: 16. the ratio in it's simplest form is 3: 1.

step-by-step explanation:

ratio: take the first number and add a colon next to it, then add the second number after that. make sure the ratio order matches up with the written problem!

simplest form: we can simplify the ratio 48 : 16 by dividing both terms by the greatest common factor (gcf).

the gcf of 48 and 16 is 16.

divide both terms by 16:

48 ÷ 16 = 3

16 ÷ 16 = 1

reducing to simplest form:

48 : 16 = 3 : 1

step-by-step explanation: yes
