(1) For each of the following experiments write sample space ‘S’ and number of sample points n(S).
(1) One coin and one die are thrown simultaneously.
(2) Two digit numbers are formed using digits 2, 3 and 5 without repeating a digits.
Solution:
(1) One coin and one die.
S = {(H, 1), (H, 2), (H, 3), (H, 4), (H, 4), (H, 5), (H, 6), (T, 1), (T, 2), (T, 3), (T, 4), (T, 5), (T, 6)}
n (s) = 12
(2) Two digit number with 2, 3 & 5 without repeating a number
S = {23, 25, 32, 35, 52, 53}
n (s) = 6
(2) The arrow is rotated and it stops randomly on the disc. Find out on which colour it may stop.
Solution:
S = {Red, orange, yellow, blue, green, purple}
n (s) = 6
(3) In the month of March 2019, find the days on which the date is a multiple of 5. (see the given page of the calendar)
Solution:
Dates that are multiple of 5.
S = {5, 10, 15, 20, 25, 30}
n (s) = 6
(4) Form a ‘Road safety commitee’ of two, from 2 boys (B1, B2) and 2 girls (G1, G2).
Complete the following activity to write the sample space.
(a) Committee of 2 boys = , (b) Committee of 2 girls = ,
(c) Committee of one boy and one girl = B1 G1, , ,
∴ Sample space = {…, …, …., …., …., ….,)
Solution:
(a) Committee of two boys = (B1, B2)
(b) Committee of two girls = (G1, G2)
(c) Committee of one boy and one girl.
= (B1, G1) (B1, G2), (B2, G1), (B2, G2)
∴ Sample space = {B1, G1), (B1, G2), (B2, G1), (B2, G2)}
