BlackZzzverrR [31]

Answer:

10.55%

Step-by-step explanation:

Given:

Initial weight of the new born baby = 3,874 grams

final weight of the baby = 3,465 grams

Now,

the current percentage of the weight loss will be calculated as:

Weight loss percentage = \frac{\textup{Loss in the weight}}{\textup{Initial weight of the baby}}\times100%

on substituting the respective values, we get

Weight loss percentage = \frac{(3874-3465)}{3874}\times100%

or

Weight loss percentage = 10.55%

What is the chance of rolling a 4 with a single die three times in a row
kumpel [21]

The key thing to remember when you're working a problem like this is that
the cube has no memory ... it doesn't know what happened on the last roll,
so the chance of any particular thing happening on the 2nd roll, or on the
100th roll, is the same as it was on the first roll.

Probability of success = (number of ways to succeed) / (total possibilities)

Number of ways for a 4 to come up . . 1
Total possible results of the roll . . . . . 6

Probability of rolling a 4 . . . . . 1 / 6 .

Probability of rolling two 4s . . . (1/6) x (1/6)

Probability of rolling three 4s . . (1/6) x (1/6) x (1/6) =  1/216 = about <em>0.46%</em> .
