To study the hormonal regulation of a metabolic line, albino rats are injected with a drug that inhibits the body's protein synthesis. In general, 8 out of 40 rats die from the drug before the experiment is over. If 10 animals are treated with the drug. What is the probability that 6 or fewer will arrive alive at the end of the experiment? What is the probability that more than 7 arrive alive at the end of the experiment? Note: Answer with at least 4 decimal places
