4. The probability that a patient recover from a delicate heart operation is 0.9. What is the probability that exactly 5 of the next 7 patients having this operation survive? Of the next 100 patients having this operation, what is the probability that (a) between 84 and 95 indusive survive? (b)fewer than to survive? 5. A co is tossed 400 times. Use the normal curve approximation to find the probability of obtaining (a) between 105 210 heads inclus (b) exactly 205 heads I fewer than 176 or more 227 heads
