Suppose we observe 80 alcoholics with cirrhosis of the liver, of whom 25 have hepatomas, that is, liver cell carcinoma. Suppose we know, based on a large sample, that t`he risk of hepatoma among alcoholics without cirrhosis of the liver is 25%. What is the approximate probability of observing at least 30 hepatomas among the 80 alcoholics without cirrhosis of the liver?

In a genetics experiment on​ peas, one sample of offspring contained 436 green peas and 373 yellow peas. Based on those​ results, estimate the probability of getting an offspring pea that is green. Is the result reasonably close to the value of 3/4 that was​ expected?

Apparently, depression significantly increases the risk of developing dementia later in lift (BBC News, July 6, 2010). In a recent study it was reported that 22% of those who had depression went on to develop dementia, compared to only 17% of those who did not have depression. Suppose 10% of all people suffer from depression.   What is the probability of a person developing dementia?   If a person has developed dementia, what is the probability that the person suffered from depression earlier in life?

In a genetics experiment on​ peas, one sample of offspring contained 433 green peas and 121 yellow peas. Based on those​ results, estimate the probability of getting an offspring pea that is green. Is the result reasonably close to the value of 3/4 that was​ expected?

In a genetics experiment on​ peas, one sample of offspring contained 396 green peas and 296 yellow peas. Based on those​ results, estimate the probability of getting an offspring pea that is green. Is the result reasonably close to the value of 34 that was​ expected?

In a genetics experiment on peas, one sample of offspring contained 367 green peas and 40 yellow peas. Based on those results, estimate the probability of getting an offspring pea that is green. Is the result reasonably close to the valuee of 3/4 that was expected?
