Binomial distribution

[ningmeng7998]

I have a binomial distribution problem like the following which I have no clue how to solve it. Is there any conditions missing from this question?

It is known that 8% of games are defective.
a. Find the probability that one of the games in the sample will be defective.
b. Find the probability that at least one of the games in the sample will be defective.

Sample size is missing!

Sample size is missing!

Thanks! In the question, there is no sample size but in the answer, it has a specific value for each question. That's why I was so confused about it. I managed to work backwards according to the answer that the sample size is 10.
