(Contd..........7)​

Answer 1

Answer:

1. i. 8/20=2/5

ii. 7/20

iii. 8/20=2/5

if.13/20

2. i. 1 because all are orange candies so total and favourable outcomes will be same.

ii. 0 because there no lemon flavoured candies in the bag

Answer 2

1.) (i) P(yellow ball) = 8/20

= 2/5

(ii) P(Brown ball) = 7/20

(iii) P(neither green not

brown) = (20- 12)/20

= 8/20

= 2/5

(iv) P(not brown) = (8+5)/20

= 13/20

-----------------------------------

2.) (i) P(takes out an orange

candy) = 1

(ii) P(takes out an orange

candy) = 0
