Answer 2

Answer:-

According to the Question

It is given that,

• No.of white = 8
• No. of black ball = 4

Total number of balls in the bag = 12 balls

━━━━━━━━━━━━━━━━━━━━━━━━━━━

Probability of getting 3 ball of White are

Favourable Outcomes = 3

$\longrightarrow$ P = No .of favourable outcome/Total No. of Outcome

$\longrightarrow$ P = 3/12

$\longrightarrow$ P = 1/4

• Hence,the probability of getting 3 white balls from bag is 1/4.

━━━━━━━━━━━━━━━━━━━━━━━━━━━

Probability of getting 2 white ball

Favourable Outcomes = 2

Total Possible Outcomes = 12

$\longrightarrow$ P = Favourable Outcomes/Total Possible Outcomes

Substitute the value we get

$\longrightarrow$ P = 2/12

$\longrightarrow$ P = 1/6

• Hence, the probability of getting 2 white ball from the bag is 1/6 .
