Please give me answer of these 7 questions?
1. If a dice is thrown once, what is the probability of getting a prime number?
2. A coin is tossed 200 times and tail is obtained 128 times. Now, if a coin is tossed at random, what is the probability of getting a tail?
3. In 100 throws of a dice, 5 is obtained 42 times. In a random throw, what is the probability of getting a 5?
4. A bag has 6 red balls and 8 green balls. A ball is drawn from a bag without looking in to the bag. What is the probability of getting a green ball?
5. What is the probability of occurrence of an event?
6. If a dice is thrown. What is the probability of getting: (i) an odd number (ii) a multiple of 3 (iii) a perfect square numbers (iv) a number less than 4?
7. Three unbiased coins are tossed together. Find the probability of getting: (i) all heads (ii) two heads (iii) one head (iv)At least two head
[hint : Possible outcomes are HHH, HHT, HTH, HTT, THH, THT, TTH and TTT Ans: 1/8 , 3/8 , 3/8, 1/2 (HHH, HHT, HTH and THH)]
Dear Student,
The solutions to your Q.1 and Q.2 have been provided below:
1) The possible outcomes when a dice is thrown =
Number of possible outcomes of a dice =6
Prime numbers on a dice are 2,3 and 5.
Probability of getting a prime number =
2) Total outcome = 200
Favourable outcome of getting a tail = 128
Probability of getting a Tail =
