Question

A bag contain 25 balls out of which 15 are red and others are blue. If probability of getting blue is​

Answer 1

Answer:

2/5

Step-by-step explanation:

if no. of red balls are 15

then,

no. of blue balls = 25-25 = 10

Probability = favourable/ total

= 10/25

= 2/5

Answer 2

QUESTION:- A bag contain 25 balls out of which 15 are red and others are blue. If probability of getting blue is

ANSWER:

Total number of balls in the bag = 25

Number of red balls in the bag = 15

Let the number of blue balls be x

So,

Number of blue balls will be

$x = 25 - 15$

$x = 10$

So the number of blue balls in the bag is 10

Probability of blue balls in the bag

P = $\sf \frac{Number \: of \: favourable \: outcomes}{Total \: number \: of \: outcomes}$

So,

P(B) $= \frac {10}{25}$

$= \frac {2}{5}$

So, the probability of getting blue balls is $\frac {2}{5}$
