Random assignment Researchers recruited 20 volunteers—8 men and 12 women to take part in an experiment involving a new drug and a placebo. They randomly assigned the subjects into two groups of 10 people each. To their surprise, 6 of the 8 men were randomly assigned to the new drug treatment. Should they be surprised? Find the probability that the random assignment would put 6 men in the new drug treatment group purely by chance.
