ute balls. A ball is drawn from the bag at
all drawn is(i) red (ii) black or white (iii) not
black.​

Answer 1

Step-by-step explanation:

i)Total no of observations =15

No.of observations =7

probability of red=7/15

ii)No.of observations=8

probability of black or white=8/15

iii)no.of observations =10

probability =10/15

Answer 2

Step-by-step explanation:

total balls =15

p (red)= 7/15

p (white or black)=8/15

p (not black)=10/15 => 2/3
