out of the box at random. What is the probability that the marble taken out will be

(ii) white ?

(iii) not green?​

Answer 1

Answer:

an electronic machine that can store, find and arrange information, calculate amounts and control other machines

Answer 2

Answer:

Total number of marbles in the box =5+8+4=17

i) P(red) = no. of red marbles/total number of marbles

P(red) = 17/5

ii) P(white) = no. of white marbles/total number of marbles

P(white) = 17/8

iii) P(green) = no. of green marbles/total number of marbles

P(green) = 17/4

P(not green) =1− P(green) = 17/13
