VIDEO EXPLANATION
ANSWER
Total number of roses in the flower pot =5+3+2=10
∴ Number of possible outcomes to select a rose at random is 10.
(i) Let 'A' be the event that the selected rose is of red colour.
No. of red roses in the flower pot =5
∴P(A)=
10
5
=0.5
(ii) Let 'B' be the event that the selected rose of of yellow colour.
No. of yellow roses in the flower pot =2
∴P(B)=
10
2
=0.2
(iii) Let C be the event when the selected rose is white in colour.
Then,
C
is the event when the selected rose is not of white colour.
No. of white roses in the flower pot =3
∴P(C)=
10
3
=0.3
Now, P(
C
)=1−P(C)=1−0.3=0.7
