Thread: [SOLVED] Probability mass function - Can anyone help me?

Some regions in Japan are particularly earthquake-prone. Suppose that in one such region,17 percent of all homeowners are insured against earthquake damage. 6 homeowners are to be selected at random; what is the probability that at least 3 of the 6 selected have earthquake insurance?

I solved then question by Binomial distribution and found the answer as 0.066. You can delete the topic...
