Step-by-step explanation:
Q : A dice is thrown at random find the probability of getting 4
answer: Numbers in a dice= 6
Number of times 4 can come between 1 to 6= 1
Therefore, the probability of getting 4 is 1/6
Q : A number less than 5
answer: Numbers in a dice= 6
Numbers less than 5 = 4 (4,3,2,1)
Therefore, the probability of getting a number less than 5 is 4/6 that is 2/3
Q : A composite number
answer: Numbers in a dice = 6
Numbers within 1 to 6 which can form a composite number= 2(3,6)
Therefore, the probability of getting a composite number is 2/6 that is 1/3.
