As of 2021 research is being conducted to study the effects of space travel on human body. For example, astronauts stay on the international Space Station (ISS) on missions and the amount of radiation they are exposed to is measured. Suppose the radiation they are exposed to on a regular six month mission follows a Normal distribution with mean 70 millisieverts(mSv) and standard deviation of 25 mSv. If the risk of cancer increases when the astranauts are exposed to more than 100mSv, what is the probability that an astranaut's cancer risk will increase during a regular mission?
A. 0.885
B. 0.115
C. 0.385
D. 0.615
