Eddi Din [679]
<h2><u>Corect option</u> :</h2>

= \color{plum}\tt(C) 7 \frac{2}{4}

<h2><u>Answer with steps</u> :</h2>

=  \tt\frac{30}{4}

=\tt  7\frac{2}{4} \:  cups

Thus, she needs \tt  7\frac{2}{4} \:  cups of water.

Therefore, the correct option is \color{plum}\tt(C) 7 \frac{2}{4}

Two dice are rolled. Define the events as follows: A : sum of 7, B : doubles, C : sum of 8
love history [14]

Answer: for a sum of 7 would either be 6 and 1, 5 and 2 or 4 and 3. you can roll a double 1,2,3,4,5,6. the sum of 8 would be 2 and 6, 3 and 5 and a double 4,

Step-by-step explanation:

well the there are six sides on a die so 6 x 2 is 12 so the max sum you can get is 12. So you take 7 and you start adding up to 7, same thing for sum of 8. since there is 6 sides and a pair of dices you will roll six doubles
