Answer:

125$

Step-by-step explanation:

if it's proportional that means it will move up or down in equal amounts

going down from 20 to 5 kg means I divided by 4

so I can also divide 500 by 4 and get 125$

Jeffrey estimates there's a 40% chance to eat pizza for dinner, it's 60% chance he'll drink cold out, and it's 30% chance to eat

Molodets [167]

Answer:

a. 75%

Step-by-step explanation:

Let "p" represent the probability that Jeffrey will eat pizza, and "c" represent the probability that he will drink cola.

We are given ...

P(p) = 0.40

P(p&c) = 0.30

The conditional probability of interest is ...

P(c|p) = P(p&c)/P(p) = 0.30/0.40 = 0.75

The probability Jeffrey will drink cola, given that he eats pizza, is about 0.75.
