The correct question is :
A Group Housing Society has 600 members, who have their houses in the campus and decided to hold a Tree Plantation Drive on the occasion of New Year. Each household was given the choice of planting a sampling of its choice. The number of different types of saplings planted were (i) Neem - 125 (ii) Peepal - 165 (iii) Creepers - 50 (iv) Fruit plants - 150 (v) Flowering plants - 110. On the opening ceremony, one of the plants is selected randomly for a prize. After reading the above passage, answer the following : What is the probability that the selected plant is (i) A fruit plant or a flowering plant ? (ii) Either a Neem plant or a Peepal plant ?
GIVEN :
No of Neem saplings = 125
No of Peepal saplings = 165
No of Creeper saplings = 50
No of Fruit plant saplings = 150
No of Flowering plant saplings = 110
Total no of saplings
= 125 + 165 + 50 + 150 + 110 = 600
TO FIND :
What is the probability that the selected plant is (i) A fruit plant or a flowering plant ? (ii) Either a Neem plant or a Peepal plant ?
SOLUTION:
Probability of an event
= Number of favourable outcomes ÷ Total number of outcomes
(i) Probability of selecting a fruit plant or a flowering plant = (No of fruit plants + No of flowering plants) / Total no of plants
P₁ = (150 + 110) / 600
= 13 / 30
(ii) Probability of selecting a neem plant or a peepal plant
= (No of neem plants + no of peepal plants) / Total no of plants
P₂ = (125 + 165) / 600
= 29 / 60
ANSWER :
(i) Probability of selecting a fruit plant or a flowering plant = 13 / 30
(ii) Probability of selecting a neem plant or a peepal plant = 29 / 60
