6. Numbers 1 to 10 are written on ten separate cards such that one number on one slip. These are mixed well and one slip is chosen from the box without looking into it. What is the probability of: (i) getting a card on which 7 is written? (ii) getting a card having two-digit number on it? (iii) getting a number less than 5? (iv) getting a number more than 5? 7. When a die is thrown, list the outcomes of an event of getting: (i) A number less than 5. (ii) A composite number. (iii) A prime number. (iv) A number more than 3. answer these for free brainliest

Answer:
1) probability of a getting 7 = 1/10 (as we want a card 7 and there are total 10 cards)
2) getting a card having two digits no.
total two digit no. cards = 10
1/10 ( as there are only one 10 digit no. out of 10 cards)
3) getting a no. less than 5
no. less than 5= 1,2,3,4
= 4/10=2/5 ( as there are 4 no. which are less than 5)
4) getting a no. more than 5
no. more than 5= 6,7,8,9,10
= 5/10= 1/2( as there are 5 no. which are more than 5)
5) getting a no. less than 5
no. less than 5= 1,2,3,4
4/6 = 2/3 ( as there are 6 outcomes in a dice)
i) a composite no.
composite no. 4,6
2/6= 1/3 ( as only 4 and 6 are composite)
ii)
a prime no. = 2,3,5 (as only these no. are prime no )
3/6=1/2
iii) no. more than 3
4,5,6
3/6= 1/2(as only these no. are more than 3)
