NCERT Solutions for Class 10 Maths exercise 15.2 – We will come across some terminologies like Experiment, Outcome, Event, etc. Any situation or phenomenon, such as tossing a coin, playing cards, rolling dice, and so on, can be used as an experiment.
Outcome: The outcome of an experiment, such as the number that appears on the dice after rolling, the side of the coin after flipping, and a card drawn from a pack of well-shuffled cards, and so on.
Event: The shuffling of all possible outcomes of an experiment, such as finding a king in an all-around rearranged deck of cards, getting heads or tails on a flipped coin, settling the score or odd numbers on dice, etc.
Sample space is the arrangement of every conceivable outcome or result, for example, getting heads or tails while flipping a coin.
NCERT solutions Class 10 Maths exercise 15.2- An elementary event is one that has only one outcome. The sum of the probabilities of all of an experiment's elementary events is one.
The probability (likelihood) of an occasion goes from 0 to 1, inclusive of 0 and 1. i.e.,
Complementary events are the main two potential results of a solitary occasion (a single event). This is closely resembling flipping a coin and checking whether it lands on heads or tails.
where E is representing event and is representing not E or complementary of the event E.
Along with Class 10 Maths chapter 15 exercise 15.2 the following exercises are also present.
Answer:
Total possible ways Shyam and Ekta can visit the shop =
(1) A case that both will visit the same day.
Shyam can go on any day between Tuesday to Saturday in 5 ways.
For any day that Shyam goes, Ekta will go on the same day in 1 way.
Total ways that they both go in the same day =
Answer:
Total possible ways Shyam and Ekta can visit the shop =
(2) The case that both will visit the shop on consecutive days.
Shyam can go on any day between Tuesday to Friday in 4 ways.
For any day that Shyam goes, Ekta will go on the next day in 1 way
Similarly, Ekta can go on any day between Tuesday to Friday in 4 ways.
And Shyam will go on the next day in 1 way.
(Note: None of the cases repeats since they are in a different order!)
Total ways that they both go in the same day =
Answer:
Total possible ways Shyam and Ekta can visit the shop =

Exercise 15.2 Class 10 Maths, depends on PROBABILITY and higher ramifications of the likelihood of an event.
NCERT book Class 10 Maths chapter 15 exercise 15.2 assists us with testing our essential idea of probability by addressing a portion of the hard and extensive inquiries identified with it.
NCERT syllabus Class 10 Maths chapter 15 exercise 15.2 sets us up for the new sorts of problems that are to come in our higher classes related to probability.
Also, See:
This exercise has tough question which tests the capability of our understanding and problem solving.
Since each dice has 6 different outcomes, and we are rolling two dice at once.
So, the total number of outcomes = 6×6 = 36
Since each dice has 6 different outcomes, and we are rolling two dice at once.
So, the total number of outcomes = 6×6 = 36
total probability of all events is = 1
probability of first and the second event is 0.45 and 0.23
probability of the third event is = 1-(0.45+0.23)=0.32
total probability of all events is = 1
probability of first and the second event is 0.45 and 0.23
probability of the third event is = 1-(0.45+0.23)=0.32
The sample space of tossing three coins at once is:
{HHH, HHT, HTH, THH, HTT, THT, TTH, TTT}
Probability of a red ball to be drawn = 0.45
Total no of balls = 20
Total no of red balls = 20 × 0.45 = 9
