Alice and Bob take turns in rolling a fair dice. Whoever gets "6" first wins the game. Alice starts the game. What are the chanc

WINSTONCH [101]

Answer:

Probability of Alice win the game is $\frac{6}{11}$

Step-by-step explanation:

When a die is rolled then probability of getting 6 is $=\frac{1}{6}$

So probability of winning the game $P(W)=\frac{1}{6}$

Now probability of losing the game $P(L)=1-\frac{1}{6}=\frac{5}{6}$

It is given that Alice starts the game

So either Alice win the game in 1st attempt or 3rd or 5th .....

So probability that Alice win the game $=P(W)+P(L)P(L)P(W)+P(L)P(L)P(L)P(L)P(W)+.....$

So $P(w)=\frac{1}{6}+\frac{5}{6}\times \frac{5}{6}\times \frac{1}{6}+\frac{5}{6}\times \frac{5}{6}\times\frac{5}{6} \times \frac{5}{6}\times \frac{1}{6}......$

Now taking $\frac{1}{6}$ common and applying sum of infinite GP $P(W)=\frac{1}{6}\times \frac{1}{1-\frac{25}{36}}=\frac{1}{6}\times \frac{36}{11}=\frac{6}{11}$

Probability of Alice win the game is $\frac{6}{11}$

Solve the compound inequality: 2x-8≥4 or 8x+7<15

MaRussiya [10]

An inequality is a sentence with <, >, ≤, or ≥ as its verb. An example is 3x - 5 < 6 - 2x. To solve an inequality is to find all values of the variable that make the inequality true. Each of these numbers is a solution of the inequality, and the set of all such solutions is its solution set. Inequalities that have the same solution set are called equivalent inequalities.
