Hello people I have this problem to solve.

The probability that a patient recovers from a rare blood disease is 0.6. If 18 people are known to have contracted this disease, what is the probability that:

(i) at least 15 survive?

p=0.6

15/18*0.6=0.5, 50%

(ii) from 5 to 10 survive?

(iii) Exactly 12 survive?

(I have attempted the first part not sure if it is correct. Really appreciate replys in regads to the answer).
