Answer 1

Answer:

total number of balls=10 red balls +6 blue balls

p(E) =10/16

=5/8

Answer 2

Answer:

the total balls are 16

the probability of drawing a red ball from 16 balls is

p(E)=no.of outcomes favourable to E/ no.of all possible outcomes

so

P(E)=10/16

5/8

the probability of drawing a blue ball is

P(E)=6/16

3/8
