Question

if a container has 15 red balls and 9 white balls and if a ball is pulled out without saying the probability of getting a red ball are ???​

Answer 1

Answer :

Probability of getting a red ball = 15/24

Explanation :

Red balls in container = 15

white balls in container = 9

Total balls = 15 + 9

Total balls = 24

We know that,

Probability of an event = Favourable Outcomes/Total number of outcomes,

Putting the values,

•°• Probability of getting a red ball = 15/24

Answer 2

S means sample space

E means events

Given

• red balls =15
• white balls =9

Total balls =15+9=24

Now,

n(s)=24 S--->total balls

n(E1)=15 E1---->red balls

Formula used:-

P(E)=n(E1)/n(S)

putting the value

P(E)=15/24

=0.625
