Đơn giản các biểu thức logic: a- p ∧ (p ∨¬q) ∧ (¬p ∨ ¬q)

creativ13 [48]

I can't conveniently copy the logical symbols you use, so I write

AND = ∧ (conjunction)

OR = ∨ (disjunction)

NOT = ¬

Tautologically,

p = (p AND q) OR (p AND NOT q)

and we can distribute the OR to get the equivalent statement

(p OR (p AND NOT q)) AND (q OR (p AND NOT q))

and again to get

((p OR p) AND (p OR NOT q)) AND ((p OR q) AND (q OR NOT q))

Now, q OR NOT q is always true, and p OR p is simply p, so we have

p = p AND (p OR q) AND (p OR NOT q)

This shows that p OR NOT q is already included in p, so our initial statement is simply

p AND (NOT p OR NOT q)

Distributing the conjunction, we get

(p AND NOT p) OR (p AND NOT q)

p AND NOT p is tautologically false, but we're considering a disjunction, so the truth value of p AND NOT q is the only value that's relevant. So, the initial statement collapses to

p AND NOT q

one town, 64% of adults have health insurance. What is the probability that 10 adults selected at random from the town all have

Katena32 [7]

Answer:

The probability that 10 adults selected at random from the town all have health insurance is 0.01153.

Step-by-step explanation:

Consider the provided information.

One town, 64% of adults have health insurance.

Let p = 64% = 0.64

Therefore, q=1-0.64=0.36

We need to find the probability that 10 adults selected at random from the town all have health insurance

Use the formula: $P(x)=^nC_r(p)^r(q)^{n-r}$

Here, the value of r is 10.

Substitute the respective values in the above formula.

$P(x)=^{10}C_{10}(0.64)^{10}(0.36)^{10-10}$

$P(x)=(0.64)^{10}(0.36)^{0}\\P(x)=(0.64)^{10}\\P(x)\approx0.01153$

Hence, the probability that 10 adults selected at random from the town all have health insurance is 0.01153.
