Determine which of the following statements are conjunctions in propositional logic with a dot (•) as the main operator. check all that apply.
(~n ⊃ ~j) • ~(~r ⊃ ~e)
(b • ~l) ⋁ ~(f • ~u)
~a • ~~e
{[(m ⊃ (~d ⋁ s)] • [~~i ⋁ (l ⊃ c)]} ≡ {[z • ~(u ⋁ h)] • [(a ⋁ r) ⊃ ~d]}
(q ⊃ v) • j
[~m • ~(m ⋁ z)] ⊃ ~[(~b • ~c) • ~g]
~{~[~(a ⋁ m) ⊃ ~e] ≡ ~(v ⊃ n)} • g
~{[~~(a • ~m) ⊃ ~~x] • ~[~(w ≡ i) ≡ ~(b ≡ g)]}
(b • l) ≡ ~(~m ⋁ ~q)
~[(d ≡ ~w) ⋁ ~(~v ⊃ j)] • [~u ⋁ (~e • ~p)]

answer: 0.95, d

step-by-step explanation:

first, you have to combine the percentages of costumers ordering pizza or salad. 25% (percent of salads ordered) plus 70% (percent of pizzas ordered) is equal to 95%. then, turn 95% into a fraction: 95/100. lastly, divide 95 by 100 and you will get 0.95, d.

x=30

step-by-step explanation:

step-by-step explanation:

a cube has 6 sides

the probability of getting 5 on the first cube is 1/6 since only one side of the cube has 5 on it.

there are 3 sides of the cube with even number on it [2,4,6]

therefore the probability of getting even number is 3/6

for both events to happen together, the probability would be

1/6 x 3/6 = 12/36

which simplifies to 1/12
