Answer 1

Answer:

Hence the probabilities are:

i)5/17

ii)8/17

iii)13/17

Step-by-step explanation:

Number of red marbles =5

Numbet of green marbles=4

Number of white marbles =8

Hence, total number of marbles=(8+4+5)

=17

Probability of getting a red marble=

number of red marbles/total number of marbles

=5/17

Probability of getting a white marble=

number of white marbles/total number of marbles

=8/17

Probability of getting a marbles that is not green= 1-(number of green marbles/ total number of marbles)

=1-(4/17)

=14/17
