Answer: Smallpox spreads rapidly and requires immediate isolation.
Explanation:
Smallpox is a highly contagious disease that can be fatal. Its symptoms are the appearance of pustules throughout the body, fever, headache, and body, among others.
The virus has an incubation period in which it is not contagious, but when pustules appear it is very contagious. The virus is spread by contact with sick patients through bodily fluids, contaminated items, and contaminated air under certain conditions.
Because the virus has a very high contagion rate, and there is no cure, in case a biochemical attack with the use of the smallpox virus, the safety protocol is to quickly isolate people who were exposed to prevent the virus from spreading.

Answer:
$0
Explanation:
Probability of getting a six and a tail:
= (1 ÷ 6) × (1 ÷ 2)
= 1 ÷ 12
Probability of not getting a six and a tail:
= 1 - (1 ÷ 12)
= (11 ÷ 12)
Therefore, the expected value is as follows:
= (Probability of getting a six and a tail × Gain) - (Probability of not getting a six and a tail × Lose)
= [(1 ÷ 12) × $110] - [(11 ÷ 12) × $10]
= $0
Hence,
For 45 times,
Money expected = 45 × $0
= $0
