1 point

A. 3/7

B. 4/7

C. 7/7

D. 1/7

​

Answer 1

$probability \: of \: an \: event \: = \frac{no. \: of \: terms \: we \: are \: interested}{total \: no. \: of \: terms}$

We want Blue balls & total number of balls is 7

Therefore,

$probability \: of \: getting \: blue \: ball \: is \: \frac{3}{7}$

So,

Option (A) is correct a answer...

Answer 2

Answer:

red balls = 4

Blue balls = 3

Total balls = 7

probability of getting Blue balls = Blue balls/total balls

= 3/7
