Answer 1

1\25

hope it is helpfulll......................

Answer 2

Answer:

here's your solution↓

sol:

S = { 7 white, 8 red , 10 blue }

n (S) = (25 )

Event A: ball containing 10 blue balls.

n (A) = 10

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

= 10 / 25

p (A) = 2 / 5

Event B : ball containing only red ball.

n(B) = 8

p(B) = n(B) / n (S)

p(B) = 8 / 25

Event C : ball containing only white ball.

n (C) = 7

p (C) = n(C) / n( S)

p (C) = 7/ 25
