Given that P(E) = 0.9, what must be true about the event E? Select the best answer. A)Event E is certain.
B)Event E is probable, but not certain
C)Event E is impossible.
D)Event E is possible, but not likely.

answer:   b

step-by-step explanation:

x2 = 16

x can not be a negative number because 16 is positive

the only answer would be positive 8  

so the possibilities of the measurement of the side of the triangle are either it is longest side or not the longest side

when it is the longest side

s < 25 + 35s < 60

if it is not the longest side

35 < 25 + s10 < sso 10 < s < 60so the perimeter70 < p < 130
