Practice Set 5.2 Algebra 10th Std Maths Part 1 Answers Chapter 5 Probability
Question 1
Maharashtra Board Solution
For each of the following experiments write sample space ‘S’ and number of sample Point n(S) i. One coin and one die are thrown simultaneously. ii. Two digit numbers are formed using digits 2,3 and 5 without repeating a digit.
Solution & Step-by-Step Answer:
i. Sample space, S = {(H, 1), (H, 2), (H, 3), (H, 4), (H, 5), (H, 6), (T, 1), (T, 2), (T, 3), (T, 4), (T, 5), (T, 6)} ∴ n(S) =12 ii. Sample space, S = {23,25,32, 35, 52, 53} ∴ n(S) = 6
Question 2
Maharashtra Board Solution
The arrow is rotated and it stops randomly on the disc. Find out on which colour it may stop.
Solution & Step-by-Step Answer:
There are total six colours on the disc. Sample space, S = {Red, Orange, Yellow, Blue, Green, Purple} ∴ n(S) = 6 ∴ Arrow may stop on any one of the six colours.
Question 3
Maharashtra Board Solution
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 & Step-by-Step Answer:
Dates which are multiple of 5: 5,10, 15,20,25,30 ∴ S = {Tuesday, Sunday, Friday, Wednesday, Monday, Saturday} ∴ n(S) = 6 ∴ The days on which the date will be a multiple of 5 are Tuesday, Sunday, Friday, Wednesday, Monday and Saturday.
