Answer 1

Step-by-step explanation:

Given that

Total no.of students = 100

a) Probability of planting rose plant

No.of favourable outcomes n(E) = 32

Total outcomes n(S) = 100

===> n(E) / n(S)

===> 32 / 100

b) Jasmine

No.of favourable outcomes n(E) = 24

Total outcomes n(S) = 100

===> n(E) / n(S)

===> 24 / 100

c) Marigold

No.of favourable outcomes n(E) = 28

Total outcomes n(S) = 100

===> n(E) / n(S)

===> 28 / 100

Total outcomes = Total students

===> (32 + 28) + (16 + 24) = 100

===> ( 60 ) + ( 40 ) = 100

===> 60 + 40 = 100

===> 100 = 100

Answer 2

Answer

(i) Sample space = 100

Rose = 32

Probab = 32/100

= 8/25

(ii) Sample space = 100

Jasmine = 24

Probab = 24/100

= 6/25

(iii) Sample space = 100

Marigold = 28

Probab = 28/100

= 7/25
