Answer:

Step-by-step explanation:

<h3>Given question:</h3>

To simplify - 

$14 + 16 \div {2}^{3} - (12 + {3}^{2} ) \div 7 + 2 \times ( - 5)$

<h3>Solution:</h3>

According to PEMDAS rule,

[First parenthesis]

$= 14 + 16 \div {2}^{3} - (12 + 9 ) \div 7 + 2 \times ( - 5)$

$= 14 + 16 \div {2}^{3} - 21 \div 7 + 2 \times ( - 5)$

[Then exponents]

$= 14 + 16 \div 8 - 21 \div 7 + 2 \times ( - 5)$

[Then multiplication]

= 14 + 16 ÷ 8 - 21 ÷ 7 - 10

[Then division]

= 14 + 2 - 3 - 10

[Then addition]

= 16 - 13

[Then subtraction]

= 3 (Ans)

What is the theoretical probability of rolling all 5 dice on the same number?

Kisachek [45]

The theoretical probability of (for example) rolling 5 ones is 1/(6^5) or approximately 0.013%. Because it doesn't matter which number we get five of we can multiply it by 6 to get 1/(6^5) or approximately 0.077%.
