Exercise 30.1 1. Write down the sample space for each of the following random experiments.
(i) Recording the card drawn from a pack of 10 identical cards numbered 1 to 10.
(ii) A circular disk is divided into three identical sectors, one of which is coloured
red, another blue and the other yellow. A pointer is fixed to the center of the
disk and the disk is spun. The colour of the sector at which it stops is recorded
(iii) Recording the number of runs scored by a batsman in a single delivery in a
cricket match
2. Determine whether each event given below is a simple or a composite event.
(i) When rolling a tetrahedronal die numbered I to 4.
(a) getting the number 3
(b) getting a side with an odd number
(ii) In a pack of 5 identical cards labelled A, B, C, D and E.
(a) drawing the card labelled A
(b) drawing a card labelled with a vowel

hey there!

if she's saving for six months, let's divide the total number we need for the trip by six, dividing it into the amount that needs to be saved for each month.

500 ÷ 6 =

she needs to save at least this amount each month, so we should use this symbol: ≥

let x be the amount she saves each month.

your final answer is x ≥

hope this !

when rotating a figure 180 degrees, imagine that you are able to take the figure and turn it clockwise or counterclockwise around a center point. to rotate a figure 180 degrees, you will need to apply the rule (x, y) → (-x, -y). start by using a coordinate grid with coordinates for each vertex of the figure. the center point of the coordinate grid is located at (0, 0), which is what you will rotate the figure around. write down the original coordinates of the shape you are going to rotate. then, apply the rule. for example, coordinate (1, 2) becomes (-1, -2). another example would be, coordinate (-4, -2) becoming (4, 2). after you change each original coordinate to the rotated coordinate, you will draw your new figure.
