Question

.
(7) There are 5 red, 2 yellow and 3 white roses in a flower pot. Select one rose from
it at random. What is the probability that the selected rose is of (i) yellow, (ii) red (iii)
not white colour.

Answer 1

Step-by-step explanation:

i) No of roses = 5 + 2 + 3 = 10

No of yellow = 2

==> Probability of yellow rose is = 2/10 = 1/5 = 0.2.

ii) No of red = 5

==> Probability of red rose is = 5/10 = 1/2 = 0.5.

iii) No of white = 3

==> Remaining = 10-3 = 7

Therefore probability of not white rose = 7/10 = 0.7.

Answer 2

$<font color=blue>$

Total no. of roses in the flower pot = 10

(i) Number of yellow roses = 2

Probability of selecting yellow roses = 2/10 = 1/5=0.2

(ii) Number of red roses = 5

Probability of selecting red rose = 5/10 = 1/2=0.5

(iii) Number of not white roses = 5+2 =7

Probability of selecting not white roses = 7/10=0.7
