Brian rolls 2 fair dice and adds the results from each. Work out the probability of getting a total that is prime. Answer THIS P

Vladimir [108]

Answer:

5/12 or 15/36

Step-by-step explanation:

Since he rolls two dice, he has a total probability of 6 times 6 = 36. The pairs, that he could add up to primes are (1,1), (2,1) * 2 (since he can get 1,2 as well), (1,4) * 2, (2,3) * 2, (3,4) * 2, (5, 2) * 2, (6,1) * 2, (5, 6) * 2. This is 1 + 2 + 2 + 2 + 2 + 2 + 2 + 2, which is equal to 15. This is a total of 15/36 possible ways, which is also equal to 5/12.

Answer:

$\frac{16 {d}^{3} }{ {c}^{2} }$

Step-by-step explanation:

${4}^{2} {c}^{ - 2} {d}^{3} {e}^{0}$

➡️ $16 {c}^{ - 2} {d}^{3} \times 1$

➡️ $16 {c}^{ - 2} {d}^{3}$

➡️ $16 \times \frac{1}{ {c}^{2} } \times {d}^{3}$

➡️ $\frac{16 {d}^{3} }{ {c}^{2} }$

What is the area of a rectangle that is 3.1 cm wide and 4.4 cm long? Enter the full-precision answer first to see the correspond

Brrunno [24]

Answer: Without rounding : 13.64 (square cm)

Rounded answer : 13.6(square cm)

Step-by-step explanation:

We know that the area of a rectangle is given by :-

$A=l\times w$ , where l is the length and w is the width of the rectangle.

Given : The dimensions of a rectangle are 3.1 cm wide and 4.4 cm long.

Then, the area of rectangle will be:-

$A=4.4\times 3.1=\dfrac{44}{10}\times\dfrac{31}{10}\\\\=\dfrac{1364}{100}=13.64\text{ cm}^2\approx13.6\ cm^2 \text{Rounded to the nearest tenth}$

Therefore, the area of rectangle = $13.6\text{ cm}^2$
