Answer 2

Answer:

Question :-

• 8 identical balls are placed at random in three bags. What is the probability that the first bag will contains 3 balls ?

Given :-

• 8 identical balls are placed at random in three bags.

Find Out :-

• What is the probability that the first bag will contains 3 balls ?

Solution :-

➸ 8 identical balls are placed at random in three bags.

$\implies \sf Probability =\: \dfrac{^8C_3 \times 2^6}{3^8}$

$\implies \sf Probability =\: \dfrac{56 \times 32}{6561}$

$\implies \sf Probability =\: \dfrac{1792}{6561}$

$\implies \sf\boxed{\bold{\red{Probability =\: 0.2731}}}$

Henceforth, the probability that the first bag will contains 3 balls is 0.2731 .

Correct options is (a) 0.2731 .

Types of probabilities :-

There are three major types of probabilities:

1. Theoretical Probability.
2. Experimental Probability.
3. Axiomatic Probability.

Formula for Probability :-

➸ Probability of event to happen P(E) = Number of favourable outcomes/Total Number of outcomes
