Suppose we have an urn containing 9 marbles. Two are red, three are green, and four are blue. We randomly select 5 marbles from the urn, with replacement. What is the probability of selecting 3 green marbles, 1 red marble, and 1 blue marbles?

probability of selecting 3 green marbles, 1 red marble, and 1 blue marbles

Step-by-step explanation:

Given data urn containing '9' marbles

given  red marbles = 2

         green marbles =3

          blue marbles = 4

Five marbles can be selected at a time from '9' marbles in   ways

by using  formula

After simplification , we get

         total number of ways n(S) = 126

The probability of selecting '3' green marbles ,one red marble and one blue marble with replacement.

let ' E' be the event of selecting '3' green marbles ,one red marble and one blue marble with replacement.

n(E) =  ways

The required probability

on simplification , we get

aloha~! my name is zalgo and i am here to you out on this amazing day. to answer your question, yes, nonzero numbers can have a greatest common factor and that would be 1. still don't get it? let me considering every number is divisible by 1 and hence every number has 1 as a factor of theirs. so, if 2 nonzero numbers didn't share any gcf (greatest common factor), they would still have a factor in common and that would be 1.

i hope that this ! : p
