Question

Sonia rolls a six sided number cube 12 times and records of she rolls a 2. What is the number of trials for this binomial experiment?

Answer 1

I think the answer is 6mbecause 6 times 2 equals 12 so maybe that's the answer

Answer 2

12

Explanation:

Binomial expression:
`P(X=r) =^nC_r p^r q^(n-r)`

Where n = No. of trials i.e. no. of times experiment occur

p= Probability of success

q= Probability of Failure

r= No. of success.

We are given that Sonia rolls a six sided number cube 12 times and records of she rolls a 2.

Since here the cube was rolled 12 times.

Thus n =12

So, No. of trials =12

Hence the number of trials for this binomial experiment is 12.
