2 questions attached in picture, #3 does not need to m=be answered, just 1 and 3 you in advance!

1) The normal human temperature is 37.2.
In here, they're asking about the temperature with one standard deviation below, so 1*0.2 = 0.2 below.
So it's 37.2 - 0.2 = 37
2) Same thing, but 3 deviations above so 0.2*3 = 0.6 above.
So it's 37.2+0.6 = 37.8
3) About 32% of the people have a temperature above 37.

Hope this Helps! :)

Logical equivalent of the give question is its contrapositive
