Answer 1

Answer:

1/2, 1/2, 0, 1/2, 1/4

Step-by-step explanation:

Total outcomes = 6 {1, 2, 3, 4, 5, 6}

Favourable outcomes of getting a number less than 4 = 3 {1, 2, 3}

P(x) = Favourable outcomes / Total outcomes

P(getting a number less than 4) = 3/6

= 1/2

______________________________

Total outcomes = 6 {1, 2, 3, 4, 5, 6}

Favourable outcomes of getting a prime number = 3 {2, 3, 5}

P(x) = Favourable outcomes / Total outcomes

P(getting a prime number) = 3/6

= 1/2

_____________________________

Total outcomes = 6 {1, 2, 3, 4, 5, 6}

Favourable outcomes of getting number 0 = 0

P(x) = Favourable outcomes / Total outcomes

P(getting number 0) = 0/6

= 0

_____________________________

Total outcomes = 2 {H, T}

Favourable outcomes of getting tail = 1 {T}

P(x) = Favourable outcomes / Total outcomes

P(getting tail) = 1/2

_____________________________

Total outcomes = 4 {R, O, A, D}

Favourable outcomes of getting letter 'A' = 1 {A}

P(x) = Favourable outcomes / Total outcomes

P(getting a letter 'A') = 1/4

Answer 2

Step-by-step explanation:

3.Total outcomes = 6 {1, 2, 3, 4, 5, 6}

Favourable outcomes of getting a number less than 4 = 3 {1, 2, 3}

P(x) = Favourable outcomes / Total outcomes

P(getting a number less than 4) = 3/6

= 1/2

4.Total outcomes = 6 {1, 2, 3, 4, 5, 6}

Favourable outcomes of getting a prime number = 3 {2, 3, 5}

P(x) = Favourable outcomes / Total outcomes

P(getting a prime number) = 3/6

= 1/2

5.Total outcomes = 6 {1, 2, 3, 4, 5, 6}

Favourable outcomes of getting number 0 = 0

P(x) = Favourable outcomes / Total outcomes

P(getting number 0) = 0/6

= 0

6.Total outcomes = 2 {H, T}

Favourable outcomes of getting tail = 1 {T}

P(x) = Favourable outcomes / Total outcomes

P(getting tail) = 1/2

7.Total outcomes = 4 {R, O, A, D}

Favourable outcomes of getting letter 'A' = 1 {A}

P(x) = Favourable outcomes / Total outcomes

P(getting a letter 'A') = 1/4
