Question

i) Assertion (A) : The probability of getting blue ball from a bag containing 3 red,
5 green and 2 blue balls is1/5
Number of favourable outcome
Reason (R) : Probability of an event E, P(E) = no. of favourable outcome /
Total number of outcome​

Answer 1

Answer:

No. of favourable outcomes are 2 and total no. of outcomes are 10.

n=10

r=2

P(E) = 2/10

= 1/5

Hence proved

Answer 2

Answer:

yes,both A and R are true and R is a correct explainati of A

p{blue}=no.of blue balls/total no.of outcomes

p{blue}=2/10

p{blue}=1/5

formula of getting probability is

p{E}=no.of favourable outcomes/total no.of. outcomes
