I believe is C and D because
C. The original rectangle width is 2m and the length is 4m. And to make the other rectangle they are adding .5 m to both the width and length
D. The original rectangle has a width of 2m and length of 4m. To make the other rectangle they are substracting 1 m from the width and length
30 out of 140
that means the equation is 30/140
that equals .2142 . . .
that moves over the 21%
Answer:
Probability is 0.831727
Step-by-step explanation:
The probability can be calculated as below
There are multiple scenarios
Scanerio 1
0 occurance & No damage = 1 - 0.2 - 0.03 - 0.001 = 0.769
Scanerio 2
1 occurance & No damage = 0.2 x ( 1 - 0.7 ) = 0.06
Scanerio 3
2 occurance & No damage = 0.03 x ( 1 - 0.7 )^2 = 0.0027
Scanerio 4
3 occurance & No damage = 0.001 x ( 1 - 0.7 )^3 = 0.000027
P(structure will not suffer any damage) = Scanerio 1 + Scanerio 2 + Scanerio 3 + Scanerio 4 = 0.769 + 0.06 + 0.0027 + 0.000027 = 0.831727
