Question

Q4) A bed of flowers consists of 100 stalks of flowers, of which 20 are lilies, h are roses (4
and the rest are tulips.
(i) Given that the probability of picking a stalk of tulip at random is find the value of h.
(ii) 10 stalks of lilies are removed from the bed. A stalk of flower is picked at random
from the remaining stalks. Find the probability that a stalk of rose is picked​

Answer 1

Answer:

i) 100-(20+h)/100

ii)

Step-by-step explanation:

i) 100-(20+h)/100            

(20+h) is the flowers except tulip and 100 is the total no. of flowers

ii) 20-10 =10 lillies left in the bed .

10+h+x = no. of flowers at present (as 10 lilies are removed)

Probability that a rose is picked = P(h)= h/10+h+x
