Hi,
just wondering if someone could please help me with this probability question?
Four colored balls in a basket: gray, green, blue, and red
A person reaches into the basket without looking, and picks out each of the four balls one at a time. What is the probability of selecting: gray, green, blue, red … in that order, without replacement?
I gave it a try but would like to have the correct answer, along with the proper formula which also displays the condition that the balls need to be selected in order
P(A)
P(gray, green, blue, red)
1/4 x 1/3 x 1/2 x 1/1 = 1/24 = 4.16%
but in order to address permutation ... you could use a factorial: 4! = 24
not sure what to do next?
thanks for any help
david
