A box contains 20 crayons. There are seven red crayons, five yellow crayons, and the rest or blue crowns suppose an experiment involves a person removing three crayons from the box. What is the probability that the person first removes a blue crayon then a red crayon and finally a yellow crayon with replacement?

good luck on your studies! : )

step-by-step explanation:

she will sew have sewn five dresses   and be 1/3 done with the sixth one in an hour.

step-by-step explanation:

3/4 of an hour=45 mins

lucy makes 1 dress per 11.25 minutes

45 mins+11.25 mins=56.25 mins

60 mins- 56.25 mins=3.75 mins

3.75 mins is 1/3 of of 11.25 mins

therefore she the other 1/3 would be part of the hour and she will have sewn 5 dresses and begun the sixth.
