Answer 1

Answer:

Given that the number of red marbles, white marbles and green marbles are 5, 8 and 4 respectively. Case (i) The probability that the marble taken out will be red. Number of red marbles in the box is 5.

Answer 2

Answer:

probability=no.of outcomes/total no. of outcomes

=5/5+8+4

=5/17

probability=no.of outcomes/total no. of outcomes

=8/5+8+4

=8/17

probability=no.of outcomes/total no. of outcomes

=4/5+8+4

=4/17
