Answer:

0.0087 probability that a freshman non-Statistics major and then a junior Statistics major are chosen at random

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

What is the probability that a freshman non-Statistics major and then a junior Statistics major are chosen at random?

There are 5 freshman non-Statistics majors out of 102 students.

Then, there will be 18 junior statistics majors out of 101 students(1 will have already been chosen). So

$p = \frac{5}{102}*\frac{18}{101} = \frac{5*18}{102*101} = 0.0087$

0.0087 probability that a freshman non-Statistics major and then a junior Statistics major are chosen at random

Mumz [18]

The total distance phoebe has to drive each day (round trip) while her usual route is closed is 42 miles

<h3>What is a Pythagoras theorem?</h3>

The square of the longest side is equal to the square of the sum of the othersides.

Before we can calculate the total distance, we will need to get the hypotenuse on both sides using the Pythagoras theorem as shown:

H^2= 12^2 + 9^2

H² = 144 + 81

H² = 225

H = 15

For the other hypotenuse

h² = 12² + 5²

h² = 144 + 25

h² = 169

h = 13 mils

The total distance = 5 + 15 + 9 + 13

The total distance = 42 miles

The total distance phoebe has to drive each day (round trip) while her usual route is closed is 42 miles

Answer:

The conclusion "T" logically follows from the premises given and the argument is valid

Step-by-step explanation:

Let us use notations to represent the steps

P: I take a bus

Q: I take the subway

R: I will be late for my appointment

S: I take a taxi

T: I will be broke

The given statement in symbolic form can be written as,

(P V Q) → R

S → (¬R ∧ T)

(¬Q ∧ ¬P) → S

¬R

___________________

∴ T

PROOF:

1. (¬Q ∧ ¬P) → S Premise

2. S → (¬R ∧ T) Premise

3. (¬Q ∧ ¬P) → (¬R ∧ T) (1), (2), Chain Rule

4. ¬(P ∨ Q) → (¬R ∧ T) (3), DeMorgan's law

5. (P ∨ Q) → R Premise

6. ¬R Premise

7. ¬(P ∨ Q) (5), (6), Modus Tollen's rule

8. ¬R ∧ T (4), (7), Modus Ponen's rule

9. T (8), Rule of Conjunction

Therefore the conclusion "T" logically follows from the given premises and the argument is valid.
