Answer 1

Answer:

1) ⅕

2) sample space: D

3) 1/36

4) P(odd & square) = ¼

5) ½

Step-by-step explanation:

1) P(A) = 6/30 = 1/5

2) sample space is the collection of all possible outcomes

{activity & distance}

3) P(5 & 5) = 1/6 × 1/6

1/36

4) odd: 1,3,5

P(odd) = 3/6 = 1/2

P(square) = 1/2

1/2 × 1/2 = 1/4

5) P(H & T) = 1/2 × 1/2 = 1/4

2 × 1/4 = 1/2

Answer 2

Answer:

see below

Step-by-step explanation:

Tally question

There are 6 marks for A out of 30 total

6/30 = 1/5

Sample space question

{run 50  run 100 run 150, swim 50 swim 100 swim 150}

We have to list all the possible choices that the spinners can land

run         50

swim      100

               150

There are 2*3 = 6 choices

Tomas Game

1/36

The normal die has 1,2,3,4,5,6

P(5) = Number of 5's / total number of numbers = 1/6

Then roll another 5

P(5) = Number of 5's / total number of numbers = 1/6

P(5,5) = 1/6*1/6 = 1/36

Joe game

1/4

1,2,3,4,5,6  triangle, square

P(0dd) = {1,3,5}/ 6 numbers = 3/6 = 1/2

P (square) = square/ total  = 1/2

Coin

1/2

HT HH TH TT

We want one heads and one tails

2 of the four

2/4 = 1/2

P (odd,square) = P(odd) * P(square) = 1/2*1/2 = 1/4
