1. Dr. Anderson and R. A. Fisher in a paper entitled "The Use of Multiple Measurements in Taxonomic Problems".

(Annals of Eugenics, 1936) found the average petal length of the iris setosa to be 1.46 cm with a standard

deviation of 0.17 cm. Find the probability that a random sample of 20 petals will have an average length of at

least 1.50 cm

answer: it's a

step-by-step explanation:

hi there!

the answer will be d: 2

answer:

step-by-step explanation:

here, the total dishes = 10

dishes having meat = 3 ( chicken, meatloaf and hamburger )

thus, the probability of having meat on the chosen dishes = number of dishes having meat / total dishes

=

therefore, the probability of not having meat = 1- the probability of having meat on the chosen dishes

=

=

=

⇒ option b is correct.
