The theoretical probability of rolling a 2 on a single roll of a number cube is .

The theoretical probability of landing on blue on a single spin of a spinner with 1 purple, 1 blue, 1 red, and 1 orange section is .

Respuesta :

Answer:

1/6, 1/4.

Step-by-step explanation:

The theoretical probability of rolling a 2 on a single roll of a number cube is 1/6,  because there are 6 numbers ( 1 to 6) on a cube.

The theoretical probability of landing on blue on a single spin of a spinner with 1 purple, 1 blue, 1 red, and 1 orange section is 1/4, because there are 4 different colours on the spinner.

Answer:

(a) 1/6

(b) 1/4

Step-by-step explanation:

Formula for theoretical probability:

[tex]probability=\frac{\text{Favorable outcomes}}{\text{Total outcomes}}[/tex]

(a)

We need to find the theoretical probability of rolling a 2 on a single roll of a number cube.

Total outcomes = 6

Favorable outcomes = 1

The theoretical probability of rolling a 2 on a single roll of a number cube is

[tex]P=\frac{1}{6}[/tex]

(b)

We need to find the theoretical probability of landing on blue on a single spin of a spinner with 1 purple, 1 blue, 1 red, and 1 orange section is

Total outcomes = 4

Favorable outcomes = 1

The theoretical probability of landing on blue on a single spin of a spinner with 1 purple, 1 blue, 1 red, and 1 orange section is

[tex]P=\frac{1}{4}[/tex]
