Answer:

P(2, then 2)  = \frac{1}{36}

P(3, then 5) = \frac{1}{36}

P(4, then odd) = \frac{1}{12}

Step-by-step explanation:

Given: A fair number cube is rolled

To find: P(2, then 2) , P(3, then 5) , P(4, then odd)

Solution:

Probability refers to chances of occurrence of some event.

Probability = Number of favourable outcomes/Total number of outcomes

Sample space = \left \{ 1,2,3,4,5,6 \right \}

Total number of outcomes = 6

P(2, then 2)  = P(2)P(2) = \frac{1}{6}(\frac{1}{6})=\frac{1}{36}

P(3, then 5) = P(3)P(5) = \frac{1}{6}(\frac{1}{6})=\frac{1}{36}

Odd numbers out of the sample space = \left \{ 1,3,5 \right \}

P(4, then odd) = P(4)P(odd) = (\frac{1}{6})(\frac{3}{6} )=\frac{1}{12}

Dima020 [189]

Answer:  x = 9

Step-by-step explanation:

The sum of three interior angles of a triangle is 180°.

(9x - 3)  + (6x)  + 48° = 180°

9x - 3 + 6x + 48 = 180

15x + 45 = 180

15x = 135
