Marysya12 [62]

Answer:

Probability of sum of pips on two faces is at least 9 = \frac{5}{18}

Step-by-step explanation:

Experiment:  Throwing two fair dice.

Total no of Outcome = 6^2 = 36

Sample space (list of outcome) is attached.

Let E be the event that sum of pips on two faces is at least 9.

Probability \:(\,Event \:E\,)\: =\;\frac{No.\: of\: favorable\: outcome\:of\: Event\: E}{Total\: No.\: of \:Outcome}

Favorable outcome are where sum is 9 , 10 , 11 and 12.

From Sample space, No. of Favorable outcome = 10

∴ Prob\: (\: E\: ) = \frac{10}{36}

Prob\: (\: E\: ) = \frac{5}{18}

Cot y, if csc y =-10/3 and cos y< 0
fredd [130]
\csc y=-\dfrac{10}3\implies\sin y=-\dfrac3{10}

\cos^2y=1-\sin^2y\implies \cos y=\pm\sqrt{1-\dfrac9{100}}=\pm\dfrac{\sqrt{91}}{10}

You're told that \cos y, so omit the positive root.

\cot y=\dfrac{\cos y}{\sin y}=\dfrac{-\frac{\sqrt{91}}{10}}{-\frac3{10}}=\dfrac{\sqrt{91}}3
