Answer: 0.52

Probability is a ratio of the number of the relevant outcomes and the total number of possible outcomes.

Let us count:

Relevant outcomes:

First pick, followed by second pick:

6 choices of red bell, followed (after replacements) by 6 choices of red bell = 6*6=36 choices

4 choices of silver followed by another 4: 4*4 = 16 choices

so in total there are 36+16=52 relevant choices

Number of all possible choices:

10 possible picks, followed by 10 possible picks: 10*10=100

The probability:

P=\frac{52}{100}=0.52

2) a) What is special about the temperature 100 °C?
aliya0001 [1]

Answer:

Absolute zero is the lowest possible temperature where nothing could be colder and no heat energy remains in a substance. Absolute zero is the point at which the fundamental particles of nature have minimal vibrational motion, retaining only quantum mechanical, zero-point energy-induced particle motion. hope this helps you
