1) A bag contains 10 purple marble, 15 yellow marbles and 5 orange marbles . You are going to remove one marble from the bag without looking. What is the probability that , you will choose a yellow marble ?
2)Twenty -three markers are put in a straight line 14cm apart from each other. How far is it from the first marker to the last?
1)
Probability (P) = Favourable Outcomes(F) / Total Outcomes (T)
Total Outcomes = 30C1 = 30
Favourable Outcomes = 15C1 =15
Hence, P = 15/30 = 0.5 or 50%
2)
Per unit distance = 14cm
n = 23
Total Distance = (n-1)*p = 22*14 = 308 cms
