Question

a bag contains 3 red balls and 4 white balls and 7 green balls what is the probability of not getting a white ball

Answer 1

Answer:

Red balls =3

white balls =4

green balls=7

therefore, sample space (S) =14

Ler A be the event of not getting a white ball.

n(A) =10

therefore,

p(A) =n(A) /n(S)

= 10/14

=5/7

Answer 2

Answer:

5/7

Step-by-step explanation:

p(e) = no.of favorable outcome/ total outcome

= 7+3/14

= 5/7
