Total number of marbles in the box

=5+8+4=17

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

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

ᴘ (red) =

$\frac{5}{7}$

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

P (white) =

$\frac{8}{17}$

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

P( green) =

$\frac{4}{17}$

P(not green)

=1− P(green)

=

$\frac{13}{17}$
