Ex 3.4, 2 There are 6 marbles in a box with numbers from 1 to 6 marked on each of them. (i) What is the probability of drawing a marble with number 2? Possible outcomes = 1, 2, 3, 4, 5, 6 Probability of getting number 2 = (ππ’ππππ ππ π‘ππππ π€π πππ πππ‘ 2)/(πππ‘ππ πππ π ππππ ππ’π‘πππππ ) = π/π Ex 3.4, 2 There are 6 marbles in a box with numbers from 1 to 6 marked on each of them. (ii) What is the probability of drawing a marble with number 5 . Possible outcomes = 1, 2, 3, 4, 5, 6 Probability of getting number 5 = (ππ’ππππ ππ π‘ππππ π€π πππ πππ‘ 5)/(πππ‘ππ πππ π ππππ ππ’π‘πππππ ) = π/π
