Question

what is the probability that you randomly choose a marble that is not read from a bag of 3 black and yellow to Red and 5 white marbles

Answer 1

given that the no. of marbles :  

red : 2

black : 3

yellow : 3

white : 5

total no. of marbles = 2+3+3+5 = 13

p(red marble) = 2/13

p(not red marble) = 1 -2/13

                             = (13-2)/13

                              = 11/13

Answer 2

Answer:

Black :- 3

Yellow :- 8

Red :- 2

White :- 5

Answer is 8/9

Step-by-step explanation:

it is because

total number of marbles are 18 ,and

they have ask for which is not red, so we will no

add red marble .

so we will add 3black + 8yellow + 5white = 16

so that will be 16/18 = 8/9

* we have divided it by 2*
