Answer:
0.1091 or 10.91%
Step-by-step explanation:
We have been given that a particular telephone number is used to receive both voice calls and fax messages. suppose that 20% of the incoming calls involve fax messages and consider a sample of 20 calls. We are asked to find the probability that exactly 6 of the calls involve a fax message.
We will use Bernoulli's trials to solve our given problem.







Therefore, the probability that exactly 6 of the calls involve a fax message would be approximately 0.1091 or 10.91%.
3. An aspirin weighs 0.018 ounces.
1 gram = 0.035 ounces
4. An aspirin is 500 milligrams.
1,000 milligrams = 1 gram
4.00 ÷ 0.25 = 16
.70 ÷ 0.05 = 14
16 quarters + 14 nickels = 30 coins
