The probability of getting a 2 and 3 in two cubes is \frac{1}{36}

<u><em>Explanation</em></u>

Total face values in each number cube is  6.

In first cube, probability of  getting a 2 is = \frac{1}{6}

and also in the second cube, probability of getting a 3 is = \frac{1}{6}  

So, the probability of getting a 2 and 3 in two cubes = \frac{1}{6}*\frac{1}{6}= \frac{1}{36}

Mr. Taylor filled out a bracket for the NCAA National Tournament. Based on his knowledge of college basketball, he has a 0.54 pr
boyakko [2]

Answer:

The probability is 2.7327 \times 10^{-9}

Step-by-step explanation:

The probability of guessing correctly, P = 0.54

Probability of not guessing correctly, q = 1 – P  

q = 1 – 0.54 = 0.46

Number of trials, n = 32

Now calculate the probability that Mr. Taylor will pick 32 correctly in first round of the game.

Below is the calculation using binomial distribution.

Probability = \left ( _{k}^{n}\textrm{} \right )P^{k}(1-P)^{(n-k)} \\= \left ( _{32}^{32}\textrm{} \right )0.54^{32}(0.46)^{(32-32)} \\= 0.54^{32} \\= 2.7327 \times 10^{-9}

If one atom of carbon weighs 1.99 × 10^−22 g and one atom of hydrogen weighs 1.67 × 10^−27 g, which element weighs more? Explain
garik1379 [7]

Answer:

The atom of carbon weighs more

Step-by-step explanation:

we have

<em>Atom of carbon weighs</em>

1.99*10^{-22}\ g=1.99*10^{-22}(\frac{10^{5}}{10^{5}})=199,000*10^{-22}(\frac{1}{10^{5}})=199,000*10^{-27}\ g

<em>Atom of hydrogen weighs</em>

1.67*10^{-27}\ g

Compare

199,000*10^{-27}\ g > 1.67*10^{-27}\ g

therefore

The atom of carbon weighs more
