Acarnival game consists of 3 dart throws at a target. the probability of scoring a hit on any one throw is 30%. using the binomial formula, find the probability of scoring 2 hits.

 Probability of scoring 2 hits = 0.63.

Step-by-step explanation:

Since we have given that

Number of dart throws at a target = 3

Probability of scoring a hit on any one throw = 30%

We will use "Binomial Distribution" i.e.

where,

n denotes number of dart throws at a target,

r denotes number of required throws

p denotes probability of success

(1-p) denotes probability of failure

So, Probability of success is given by

Probability of failure is given by

We will use "Binomial Distribution" i.e.

Hence, Probability of scoring 2 hits = 0.63.
