A number cube is rolled twice. What is the probability of getting a 6 on the first roll,
then a number less than 5 on the second roll?

A. 5/36
B. 1/9
C. 2/3
D. 1/36

Respuesta :

Answer:

b. 1/9

Step-by-step explanation:

1. 1/6 is the probability of rolling 6

2. 4/6 is the probability of rolling less than 5

3. Multiply them: [tex]\frac{1}{6} x\frac{2}{3}[/tex]

4. Answer: 1/9

The probability of getting a 6 on the first roll, then a number less than 5 on the second roll should be option b.

Calculation of the probability:

since

1/6 should be considered as  the probability of rolling 6

And, 4/6 is the probability of rolling less than 5

So [tex]= 1\div 6 \times 2\div 3[/tex]

= 1/9

Hence, the option b is correct.
