A disjunction is false if and only if both statements are false.
<span>Otherwise it is true
</span>
<span>4 · 3 = 11 or 4 + 5 = 10 → F ∨ F
</span><span>7 -2 = 5 or 2 · 4 = 7 → T ∨ F
</span><span>1 + 8 = 12 or 5 · 3 = 15 → F ∨ T
</span>7 · 2 = 14 or 4 + 5 = 9
→ T ∨ T
Therefore your answer is <span>4 · 3 = 11 or 4 + 5 = 10</span>
there are 8 letters
2/8 to get i on the first draw
1/7 to get i on the second draw (no replacement)
2/8 * 1/7 = 2/56
1/28
The probability is 1/28
F(-3)=(-3)2 - 1 / -3 + 4
f(-3)= -6 -1 / -3 + 4
f(-3)= -7/1
f(-3)=-7
The vertex of f(x)=-x2+4x-8 is (2, -4)
Where is the rest of the question?
