Ex 3.4 Class 7 Maths Question 2.
\nThere are 6 marbles in a box with numbers from 1 to 6 marked on each of them.
\n(i) What is the probability of drawing a marble with number 2?
\n(ii) What is the probability of drawing a marble with number 5?
\nSolution:
\n(i) Total number of marbles marked with the number from 1 to 6 = 6
\n\u2234 n(S) = 6
\nNumber of marble marked with 2=1
\n\u2234 n(E) = 1
\n\u2234 Required probability = \\(\\frac{n(\\mathrm{E})}{n(\\mathrm{S})}=\\frac{1}{6}\\)<\/p>\n

(ii) Number of marble marked with 5 = 1
\n\u2234 n(E) = 1
\n\u2234 Required probability = \\(\\frac{n(\\mathrm{E})}{n(\\mathrm{S})}=\\frac{1}{6}\\)<\/p>\n
